The NHBS Guide to Grasshoppers and Bush-crickets

Here in the UK, we have 11 species of grasshopper and 23 species of cricket (around ten of these being bush-crickets), both subfamilies belonging to the order Orthoptera. Although similar in appearance, the two can be separated by their antennae – grasshoppers have short, stout appendages and bush-crickets have longer, thinner antennae. Bush-crickets also have a larger body size than grasshoppers, growing up to 5cm in length, and females have a distinctive ovipositor used to lay eggs.

Here, we look at a few species of grasshoppers and bush-crickets found in the UK, detailing ways to ID them and where they can be found.

Common Field Grasshopper (Chorthippus brunneus)

A brown grasshopper is sat on a small twig, it is dull in colour but has a vibrant yellow-orange abdomen under a darker wing — Image by Gilles San Martin via Flickr

ID Notes: Up to 2.5cm in length. This grasshopper is usually a mottled brown colour, but can vary from brown to grey, orange and purple. It has barring on the sides, and a very hairy underside which is the most straightforward way to identify this species. It is winged and able to fly. Their song consists of short, single chirrups repeated at short intervals.

Distribution: Common and widespread throughout Britain. Common Field Grasshoppers can be seen from May to October on short vegetation in dry, warm days. They can be found in grassy areas including farmland, grassland, heathland, moorland, towns and gardens.

Meadow Grasshopper (Chorthippus parallelus)

ID Notes: Up to 2.3cm in length. Meadow Grasshoppers are usually green in colour, with some individuals brown or pink-purple coloured (pictured above). The wings are often brown and are long in males, whereas female wings are short and do not reach the end of the abdomen. This species has distinctive black knees and a dark brown stripe running across the flank to the eye. They are similar in appearance to Common Field Grasshoppers, but lack a hairy underside, which can be used to distinguish them from one another. Their song is a burst of around ten chirrups, making a ‘rrr’ sound.

Distribution: Common and widespread throughout Britain. Meadow Grasshoppers can be seen from April to October in damp pastures with long grass. They can also be found in meadows, grassland, heathland and moorland.

Common Green Grasshopper (Omocestus viridulus)

ID Notes: Up to 2.3cm in length. As the name suggests, this species is mostly green in colour, but males can also be olive brown. Lines on the shoulders are incurved and white or cream in colour. Common Green Grasshoppers are winged and can fly, but their wings do not exceed the body’s length. They produce a long, loud ticking song which can last for 20 seconds or more and is reminiscent of a fast-paced freewheeling bicycle.

Distribution: Common and widespread throughout Britain, although a little patchier in the lowlands. This species appears early in spring and can be seen from April to September. It can be found in coarse, moist grass in meadows, woodland rides, hillside pastures and farmland.

Mottled Grasshopper (Myrmeleotettix maculatus)

ID Notes: Up to 2cm in length. This small grasshopper is most easily identified by its antennae – males’ are club-tipped, and females’ have a thickened tip. The body has several colour variations including green, brown, grey and orange. Their song is a repetitive ‘zrr’ ‘zrr’ sound lasting around ten seconds before stopping abruptly.

Distribution: Widely distributed across the UK, but uncommon. Mottled Grasshoppers can be found from April to October in areas of dry, short grass with access to rocks or bare ground, including grasslands, heathland and old quarries.

Oak Bush Cricket (Meconema thalassinum)

A small, lime green cricket is sat on three leaflets. It has very long, flexible antennae that are trailing off of the leaf and long, yellow legs — Image by Alison Day via Flickr

ID Notes: Up to 1.7cm in length. This species is the UK’s only native, arboreal cricket. It has a slender, lime green body with a yellow-orange or brown strip running along its back. Both sexes are fully winged, with wings reaching the end of the abdomen. Females have a long, upturned ovipositor and males have a pair of shorter, rounded claspers. The males do not produce a song, but instead drum their hind legs on nearby leaves.

Distribution: Common, found in England and Wales. The Oak Bush Cricket is common in the midlands and the south but is absent further north. It can be found in the canopy of mature trees in woods, hedges, garden shrubs and other deciduous trees from June to November.

Dark Bush Cricket (Pholidoptera griseoaptera)

A dark brown cricket is standing on a large leaf. It has very long thin antennae and a curved, pointed spine at the end of its body. Its long rear legs are outstretched, standing on another leaf — Image by Alison Day via Flickr

ID Notes: Up to 2.1cm in length. This species is typically reddish to dark brown, with occasional yellow green through the abdomen and a paler area along the top of the thorax. It has very small forewings and long, hair-like antennae. Females have a large, upcurved ovipositor.

Distribution: Fairly common in central and southern England and Wales, where it can be found in woodland, hedgerows, grassland, farmland, towns and gardens. It can often be spotted in large numbers around bramble patches, where they are basking in the sun.

Roesel’s Bush Cricket (Metrioptera roeselii)

ID Notes: A short-winged and usually flightless species, Roesel’s Bush Crickets are typically dark brown or yellow in colour, sometimes tinged green. They have a green face, slightly orange legs and a cream-coloured margin to their thorax, with two or three yellow spots on the side. Their monotonous song is recognisable for its long, mechanical sound.

Distribution: Common, found mostly in the southeast of the UK, but currently expanding its range north and west. This species can be found from June to October in rough grassland, scrub, salt marshes and damp meadows.

Great Green Bush Cricket (Tettigonia viridissima)

ID Notes: This large bush-cricket can easily be distinguished by its size, growing up to 7cm long. It is a vibrant green with an orange-brown stripe running the length of its back. Their wings are typically longer than the abdomen, and females have a long, downward curved ovipositor. This species has a loud, long song which sounds like a high-pitched sewing machine running continuously.

Distribution: Common throughout south England and Wales. It can be found from May to October in scrub, woodland, grassland and heathland, with a preference for light, dry soils.

The NHBS Guide to UK Centipedes and Millipedes

If you look under logs, stones or through piles of leaf litter, you may find a Myriapod (a type of arthropod with many legs, related to insects and spiders). Although these misunderstood animals may strike fear in some, these invertebrates play a vital role in maintaining our ecosystems. One of their main roles lies in nutrient cycling, where they feed on organic matter and detritus, breaking materials down into a simpler form and thus releasing nutrition back into the soil. They also play an important role, both as predators and prey, in the ecosystem’s food chain and are often celebrated for their effectiveness as a natural biocontrol agent.

The UK has more than 50 species of centipede. This group are generally carnivorous and have around fifteen pairs of legs, with one pair present on each body segment. They have large forcipules, a pair of pincer-like, modified front legs that are used to inject venom into their prey. There are around 65 species of millipede in the UK, which can be distinguished by their shorter, more clubbed antennae, the absence of forcipules and their tendency to have two pairs of legs on most body segments.

Here, we look at a few species of centipede and millipede that can be found in the UK, detailing ways to ID them and where they can be found.

Common Centipede (Lithobius forficatus)

ID Notes: Also known as the Brown Centipede, Lithobius forficatus is one the largest centipede species in the UK, growing up to 3cm in length. They have long, thin segmented bodies that are a reddish-chestnut brown colour. Each segment has one pair of legs, with 15 pairs in total. They have long antennae and an elongated pair of back legs, giving the illusion of a second pair of antennae at the rear of the body. This species is best identified by thorned projections on the outer edges of the 9th, 11th and 13th segments.

Distribution: Very common and widespread across the UK. This species can be found year-round but is most numerous in spring and autumn. They can be found in a variety of habitats, including woodland, grassland and gardens, and will spend most of the day nesting in soil or sheltered areas under stones, bark or dead wood before emerging at night to hunt for prey.

Stone Centipede (Lithobius microps)

ID Notes: Similar in colour to the Common Centipede, Lithobius microps is a ground-dwelling species that is usually chestnut brown in colour, although red and orange varieties can also be found. It is much smaller than its common cousin, reaching around 1cm in length, and its 15 pairs of legs are slightly shorter and paler than those of the Common Centipede.

Distribution: Fairly common in the south of Britain. This fast-moving species can be found year-round in gardens and bare soil in rotting wood and under rocks and stones.

Banded Centipede (Lithobius variegatus)

ID Notes: Measuring up to 3cm in length, this small, yellow-brown centipede is easily distinguished by the banding on its legs – these alternate pale and dark, are usually brown in colour and are more obvious on the rear pairs. It has a dark band running centrally along its back and much larger jaws when compared to other Lithobius species.

Distribution: Widespread and common in the UK. It can be found year-round living under stones and decaying plant matter during the day, and is commonly found in garden compost heaps.

Flat-backed Millipede (Polydesmus angustus)

ID Notes: This millipede grows to around 2.5cm in length, with a width of 4mm. It has a long, flat body with around 20 body segments, each containing between one and two pairs of legs. It is orange-brown in colour and has numerous off-white coloured legs.

Distribution: Widespread and common in the UK. They can be found in almost any environment in which millipedes occur, with frequent sightings in woodland under dead wood and leaf litter.

Striped Millipede (Ommatoiulus sabulosus)

ID Notes: Up to 3cm in length, this species is one of the largest millipedes found in Britain. It is thick and cylindrical in shape, usually dark brown to black in colour. It has orange coloured stripes running the length of its body on its back, but these can sometimes appear as a series of orange patches.

Distribution: Common and widespread throughout Britain and Ireland. The Striped Millipede can be found year-round in meadows, fields and woodland under leaf litter and logs. It is also known to climb on walls and trees to feed on algae and can be found during the day.

White-legged Snake Millipede (Tachypodoiulus niger)

ID Notes: The White-legged Snake Millipede can grow to around 6cm in length. It is tubular-shaped with a shiny black body and contrasting white legs, of which there are around 100. Immature millipedes are brown, often with pale, longitudinal stripes down the back. It has a pointed telson (legless tail segment) at the end of its body.

Distribution: Common and widespread in the UK. This species can be found year-round in most habitats containing millipedes, including woodland and gardens, or areas with rocks or rotting vegetation to provide cover.

The NHBS Guide to UK Solitary Bees

There are around 270 bee species in the UK, and over 90% of these are solitary – they do not nest in colonies, do not produce honey and don’t have a queen. Instead, these bees lead solitary lives, only coming together to mate. The group can be divided into ground-nesting species, found on lawns, paths and loose soil, or aerial nesters which utilise hollow plant stems, dead wood and man-made bee hotels to build a nest for larval bees.

Here we look at a small selection of these important pollinators found in the UK, outlining ways in which they can be identified and where they can be found.

Mason Bees

Mason bees is the name used to refer to bees of the genus Osmia. There are around 500 different species of mason bee across the world, and around 20 of these can be found in the UK. This group gets their name from their use of mud or clay in nest building, which takes place in naturally occurring gaps or cracks, and other small, dark cavities. Some species of mason bee will also use hollow stems or bore holes made by wood-boring insects.

Red Mason Bee (Osmia bicornis)

Distribution: Widespread and common throughout England and Wales. Rarer in Scotland. These bees can be found from early spring in grassland, farmland, towns and gardens. Red Mason Bees are common in built environments and are often seen nesting in the crumbling mortar of old walls. This species is also a common inhabitant of bee hotels.

Identification: These fluffy bees grow up to 1.1cm long and are typically identified by dense, gingery hair. On both males and females, the head and thorax are brown with an orange abdomen. Males are typically smaller than their female counterparts and have a distinctive white tuft of hair on the head. Female Red Mason Bees have dense orange hairs on the abdomen, with pollen collecting hairs on the underside. This species also has a pair of short, distinct horns on the head.

Red-tailed Mason Bee (Osmia bicolor)

Distribution: Nationally rare in the UK. Red-tailed Mason Bees can be found from March to July in the south and east of England and south Wales. This species occurs exclusively on calcareous grassland over chalk or limestone, in quarries, grassland and brownfield sites.

Identification: This species has dense, black hair on the head and thorax. Bright orange-red hair is present on the abdomen and the lower legs, forming stripes of orange and brown on the upper abdomen. Males are slimmer and less vibrant than females, and can have pale, duller brown hairs on their head, thorax and abdomen.

Mining Bees

Sometimes referred to as digger bees, this group are named after their burrowing behaviours in which they create their nests. There are roughly 65 species in the Andrena genus, making mining bees the largest bee genus in Britain.

Tawny Mining Bee (Andrena fulva)

Distribution: Widespread and common in England and Wales. Populations are growing in Scotland. This species can be found in farmland, heathland, parks, towns and gardens from March to June.

Identification: Similar in size to a honeybee, with dense orange hair and a black face. Females tend to be larger and have a thick, orange coat covering the upper thorax and abdomen. The underside is covered with black hair, along with the head and legs. Males are trickier to identify but are generally smaller and slimmer. They have long mandibles and are browner in colour, but can be distinguished by white tufts of facial hair on the head.

Ashy Mining Bee (Andrena cineraria)

Distribution: Common and widespread across Britain and Ireland. Can be found nesting in gardens, woodlands, riverbanks and urban environments from March to July.

Identification: A distinctive bee growing up to 15mm in length. Females have two, broad grey bands at the top and bottom of the thorax. The abdomen is sparsely haired, revealing a glossy black exoskeleton and the legs are covered with dense black hair. They also have a patch of ashy grey hair on their faces. Males have similar markings but are generally smaller in size. The bands are less distinct, and they have a spread of grey hair across their thorax.

Leafcutter Bees

Named for their nesting habits, these bees are known to cut circular leaf pieces to use as building material for their nests. Leafcutter bees lay their eggs in natural tree cavities where they use up to 40 pieces of harvested leaves and petals to create a chamber for safe incubation. There are seven different species of leafcutter bee in the UK – they can be found nesting in beetle holes, plant stems, deadwood, cliffs or old walls.

Patchwork Leafcutter Bee (Megachile centuncularis)

Distribution: Widespread and common throughout the UK, although less common in the north. Patchwork Leafcutter Bees can be found in a range of habitats from April to August, including grassland, farmland, woodland, towns and gardens. This species is strongly associated with willowherbs, honeysuckle and roses.

Identification: Easily identified by the vibrant yellow-orange pollen brush under the abdomen, extending right to the tip. This species is a similar size to honeybees, growing up to 13mm. The female has defined white bands across the abdomen. Males are more challenging to identify – similar in appearance to a dark honeybee, with the characteristic vibrant underside and tan coloured hair around their thorax.

Willughby’s Leafcutter Bee (Megachile willughbiella)

Distribution: Common and widespread across Britain. Frequently observed in brownfield sites from June to August. This species is also readily found in bee hotels.

Identification: Up to 18mm in size, Willughby’s Leafcutter Bees are similar in appearance to Patchwork Leafcutter Bees. They appear similar to dark honeybees, with little hair. The species varies in shades of black, with orange and gold throughout the coat and an orange pollen brush. Males can be distinguished by oversized front basitarsi, giving the appearance of white, wooly mittens.

The NHBS Guide to UK Jellyfish and Hydrozoa Identification

Jellyfish, or jellies (as some scientists would like them to be called), are mainly free-swimming members of the subphylum Medusozoa. The jellyfish form is actually the medusa phase of certain gelatinous Medusozoans, many of whom also have several other phases, including a sedentary polyp phase. Jellyfish are found across the world and fossil evidence shows that they have been in existence for at least 500 million years. The largest is thought to be the Lion’s Mane Jellyfish, whose tentacles have been recorded up to 36.6m long. The smallest is thought to be the Irukani Jellyfish, which measures one cubic centimetre (1cm3).

Hydrozoa are small, predatory animals that can live solitarily or in colonies. Mostly, they are permanently attached to the substrate, but some are pelagic (free-swimming). The individual animals of colonial hydrozoa are called zooids and they can play different roles within the colony, such as digestion (gastrozooid), reproduction (gonophores) and tentacle-bearing zooids (dactylozooids).

Both jellyfish and hydrozoans are part of the phylum Cnidaria. Most species within this phylum have stinging cells called nematocysts, located mainly on the tentacles. True jellyfish, however, also have them around the mouth and in the stomach. Also called cnidocytes, these explosive cells deliver a structure containing toxins, which can act as a weapon against predators or to immobilise or kill prey.

Cnidarians are thought to be amongst the most important planktonic and benthic predators in the sea as, when abundant, they are major consumers of plankton, including fish larvae and crustaceans. They also prey on small fish and other jellyfish species. Most are planktonic creatures, unable to swim against the current ,and are therefore carried by the currents throughout the oceans. Because of this, they cannot actively hunt prey, so many species have developed incredibly long tentacles to increase their chances of catching food.

This blog covers the identifying features of a number of species of Jellyfish and hydrozoa you are likely to find in UK waters, as well as the seasons they are present.

Jellyfish

Moon Jellyfish (Aurelia aurita)

Season: All year

What to look for: This species is translucent, with a white tinge to its bell. Its most recognisable feature is the four horseshoe shapes or circles visible through the top of its body. These are reproductive organs called gonads, and can range from white to purple in colour. Moon Jellyfish have thin, short tentacles hanging from the edges of the bell, as well as four feeding appendages called oral arms which surround the mouth beneath the bell.

Compass Jellyfish (Chrysaora hysoscella)

Season: May to October

What to look for: Yellowish-white jellyfish with a brown fringe around the bell. Its name comes from the brown markings on the top of the bell, where v shapes radiate out from a central point, resembling a compass. Their oral arms are fringed, and they have long, thin tentacles around the edge of the bell.

Lion’s Mane Jellyfish (Cyanea capillata)

Season: May to October

What to look for: Translucent brown jellyfish, although it can also be reddish. The bell of this species has eight lobes, rather than being simply circular. This species has a thick ‘mane’ consisting of hundreds of hair-like tentacles attached to the bell’s subumbrella. They also have a number of frilly oral arms extending from around the mouth, which are shorter than the tentacles.

Did you know? The Lion’s Mane Jellyfish is one of the longest animals in the world; its tentacles can grow to over 30m long!

Barrel Jellyfish (Rhizostoma pulmo)

Season: May to October

What to look for: The Barrel Jellyfish is a large translucent jellyfish, with a huge mushroom-shaped bell. They lack tentacles on the edges of their bell, but they do have a violet fringe containing sensory organs with eight frilly tentacles below this.

Blue Jellyfish (Cyanea lamarckii)

Bluefire jellyfish in Brofjorden at Sandvik. — Bluefire jellyfish (Cyanea lamarckii) by Ann-Sophie Qvarnström, via flickr.

Season: May to October

What to look for: Also called the Bluefire Jellyfish, this species can vary in colouration depending on maturity, so may have a blue, purple or yellow tone. Yellow toned individuals may be confused with Lion’s Mane Jellyfish, however Blue Jellyfish can be distinguished by their smaller size and fewer tentacles. They can grow up to 30cm in length, although most individuals usually measure between 10–20cm. They can have a dark blue, circular, sun-like pattern on the top of their bell, as well as long marginal tentacles and several, frilly oral arms.

Mauve Stinger (Pelagia noctiluca)

Season: July to October, but dependent on weather and ocean currents

What to look for: This species has a dome-shaped bell that is covered in wart-like stinging cells and eight marginal tentacles emanating from the edges of the bell. They also have four long oral arms that also have wart-like nematocysts down one side; while the other side is crenulated, giving the arms a slightly frilly appearance. The colour of this species varies from mauve, pink and purple to light brown or yellow.

Hydrazoa

Portuguese Man o’ War (Physalia physalis)

Portuguese man o' war swimming on the surface. — Portuguese man o’ war by Joi Ito, via flickr.

Season: September to December

What to look for: The Portuguese Man o’ War is not one animal, but a colony organism made up of four polyp types. The uppermost polyp is the gas-filled structure called the pneumatophore, which sits on the surface of the water and is the most visible. It is mostly transparent, with a blue, pink or purple tinge. The top edge of this structure resembles a sail. Two other polyps cooperate to allow the colony to hunt and feed: the polyp containing gastrozooids and the tentacles (dactylozooids). These tentacles can be a variety of colours, such as blue, purple or clear, and hang down below the surface. The final polyp type is the gonodendron, the compound reproductive structure that can be found hanging just below the pneumatophore. These can also vary in colour, and are often deep blue, pink or purple.

By-the-wind-sailor (Velalla velalla)

Season: September to March

What to look for: This species is also a colonial hydroid made up of multiple polyps, and contains gonozooids and dactylozooids. It has an oval disc that is deep blue in colour and acts as a float, with short tentacles hanging down from it. A semi-circular fan is set atop the float like a sail which aids its movement through the water via wind power.

The NHBS Guide to Thistles

Distinctively prickly with pink or purple flowers, thistles belong to the largest family of flowering plant in the UK (with the exception of the grasses) – Asteraceae. These common plants are found throughout Britain and Ireland, providing key services for invertebrates who seek safety in the sharp spines. The leaves and nectar of thistles are also excellent sources of food for other groups, including pollinators and Painted Lady caterpillars, and several bird species are known to eat the seeds.

Here we take a look at a selection of thistles found throughout the UK, highlighting their distribution and ways in which they may be identified.

Creeping Thistle (Cirsium arvense)

Creeping Thistle by hedera.baltica via Flickr

ID Notes: This perennial flower is named for its far-reaching, creeping roots. The leaves are smooth and grey-green in colour, with wavy, spined edges. The stems are smooth, neither spined nor winged. The flowerheads produce small, pale pink flowers (1.5–2.5cm) in small clusters with pear-shaped bases covered with phyllaries pressed against the flowerhead, curving outwards.

Distribution: Widespread and common throughout Britain and Ireland. Creeping Thistles can be found from June to October on rough grassland, roadside verges and field edges – a preference for disturbed and cultivated ground is observed in this species.

Spear Thistle (Cirsium vulgare)

Spear Thistle by Andreas Rockstein via Flickr

ID Notes: This thistle is particularly attractive to pollinators, who are often seen feasting on the deep pink flowers. The large flowerheads (up to three may be present per stem) sit on a bulbous, spiked base with long, spreading phyllaries. The leaves of a Spear Thistle have long, lanceolate segments tipped with spines, and the upper surface is bristly. The stem is covered with light hair and sporadic spiny wings.

Distribution: Widespread and common throughout Britain and Ireland. It can be found from July to October on disturbed ground such as roadside verges, field edges and pastures.

Welted Thistle (Carduus crispus)

Welted Thistle by Joost J. Bakker IJmuiden via Flickr

ID Notes: This plant has small, red-purple flowerheads that are clustered together. The base of the flower head has spiny, protruding bracts and the phyllaries project outwards. The branched stems have several rows of spiny wings, and the leaves have broader lobes than is typical for other thistles, with spiny margins.

Distribution: Widespread throughout Britain, except Ireland. This species shows a preference for nutrient-enriched substrates, including brownfields, field margins, meadows and beside streams.

Marsh Thistle (Cirsium palustre)

Marsh Thistle by Gertjan van Noord via Flickr

ID Notes: Growing up to 2m in height, this large thistle is easily identified by its purple tinge. The flowerheads are small and are found in large clusters, with small reddish-purple or white flowers and the phyllaries are pressed against the flower head, with tips facing downwards. Leaves are more slender and shorter, with hair visible on the upper surface, they are often tinged purple on the margins and have many spines.

Distribution: Widespread throughout Britain and Ireland, and can be found in marshes, damp grassland and meadows.

Meadow Thistle (Cirsium dissectum)

Meadow Thistle by Thibault Lefort via Flickr

ID Notes: Each Meadow Thistle has one flower head on a cottony stem, growing up to 80cm tall – the solitary flower has purple-tipped, long bracts and the base covered with light, white hair. The stems are not winged, and basal leaves are toothed in a rosette formation. The remaining leaves are finely toothed, without spines, and have light hair on top, with a white, cottony appearance underneath.

Distribution: Most common in the south of the UK, with strongholds in the south-west and south Wales. Meadow Thistles are scarce towards the north. They can be found in bogs, fens, grassland and meadows.

Musk Thistle (Carduus nutans)

ID Notes: Growing up to 2m in height, the Musk Thistle is recognised for its greyish-green colour. The flowerheads are large (3–5cm across), often nodding to one side after maturity, and have long, spiny phyllaries and two-lipped petals. The leaves are short and twisted, with spines present on the toothy lobes and are often woolly underneath.

Distribution: Widespread throughout Britain, but absent from Scotland and Ireland. Most commonly found on calcareous soil from May to September.

Woolly Thistle (Cirsium eriophorum)

Woolly Thistle by Olive Titus via Flickr

ID Notes: The Woolly Thistle gets its name from its wool-like covering. The leaves are ladder-like and narrow, tipped with spines and are white underneath. The stems are wingless and are covered in cobweb-like hairs, producing a single large flowerhead. The phyllaries on the flower base are downward curved, spread throughout the cobwebbing.

Distribution: Widespread throughout Britain, with strongholds in the Yorkshire Wolds and the Isle of Wight. The ‘queen of thistles’ often prefers chalky soils.

The NHBS Guide to Clovers

Often perceived as a pesky weed in garden lawns, clovers are low-growing, common plants belonging to the family Fabaceae – also home to beans, peas and legumes. These drought resistant plants can be found throughout Britain and Ireland in a range of habitats and are key food sources for a number of pollinators.

Here we look at a selection of clovers found in Britain, highlighting their identifying characteristics and where they can be found.

White Clover (Trifolium repens)

ID Notes: A familiar ‘weed’ of grassy spaces, the White Clover is easily recognised for its distinctive trefoil leaves – three leaflets bearing white markings. The flowers are white, sometimes pink toward the tips, with rounded heads made of many tubular blooms. Left to grow, this plant can grow up to 40cm in height, and is associated with Common Blue Butterflies (Polyommatus icarus) and bumblebees.

Distribution: Common and widespread throughout Britain and Ireland. This plant can be found in grassy areas from May to October, including gardens, roadsides, meadows and parks.

ID Notes: These pale pink flowers (2–3cm in size) are covered with small soft hairs giving it a cottony appearance, like a hare’s paw, as the name would suggest. The trifoliate leaves are divided into three leaflets, narrower than other clovers and covered in fine hair. The stalks are also covered in fine, white hair.

Distribution: Fairly common in England and Wales, with a preference for coastal areas. Hares-foot Clover is uncommon in Scotland and Ireland. It can be found from June to September in dry grasslands, meadows, sandy soils and coastal areas.
