On 2nd September last year, a terrible fire destroyed the National Museum of Brazil in Rio de Janeiro. Alongside the vast collection of irreplaceable natural history specimens, the fire also destroyed books and equipment used by the Museum’s researchers for ecological research and wildlife conservation.
Thankfully as museum curator, Débora Pires, wrote shortly after the incident: “The brains did not burn; we are working with a positive agenda!”
NHBS were approached by our former director Alan Martin, who provided a list of products which the malacology, arachnology, entomology and lepidoptera departments needed to get back on their feet. Alan, now secretary of the Brazilian Atlantic Rainforest Trust (BART) has close links with many researchers at the museum.
Following this, we decided to coordinate an effort to provide the items that are most critical to their research. We contacted suppliers asking them to contribute and we agreed to supply our own manufactured products, and cover shipping costs of all donated items.
The response from suppliers was fantastic, as the majority were happy to donate all, or most of the items requested. We would like to give huge thanks those who have donated so far: Elsevier, BIOTOPE Parthenope, Brunel Microscopes Ltd, BugDorm, CABI Publishing, Harvard University Press, the Royal Museum for Central Africa, Watkins & Doncaster and finally EntoSphinx. So far, we have received just over £2,000 worth of items, with more to follow.
“I’m really sorry to hear such devastating news. This is truly awful and it’s good to see you are providing such great support to them. We would be happy to send out the [requested] book gratis.” – Linda Jackson, Elsevier

National Insect Week is organised by the Royal Entomological Society and occurs every two years. In 2018 it takes place from 18th to 24th June.
Following the shocking news in 2017 which revealed recent drastic declines in insect numbers, insect and invertebrate biodiversity has never been more critical. National Insect Week aims to inspire people of all ages and backgrounds to learn more about insects and the vital roles they play in almost every ecosystem on earth.
To celebrate National Insect Week hundreds of events will be occurring throughout the UK, ranging from Bioblitz days, insects walks, workshops and even the chance to dine out on edible insects. Take a look at the interactive map on the official National Insect Week website to see what’s happening where you live. Or why not organise your own event? Don’t forget to submit the details on the website though so that it can be added to the map!
New to the world of insects?
Why not get started by watching the following videos from the Royal Entomological Society. They provide a brief introduction to the various groups of insects and explain why they are so vitally important to life on earth. If you’re eager to learn more then you can read about all of the main orders of insects here.

Moth Night 2017 takes place from Thursday 12th to Saturday 14th October. Organised by Atropos and Butterfly Conservation, this annual event aims to increase public awareness of moths and also to provide an organised period of recording by moth enthusiasts around the UK. The theme of the 2017 Moth Night is “Ivy and Sugaring”.
Why “Ivy and Sugaring”?
During September and October, ivy blossom provides a major source of nectar and pollen and so attracts a wide range of insects including honey bees, late-season butterflies, hoverflies and moths. Searching ivy blossom by torchlight is therefore a useful way of finding and surveying moths at this time of year and can be particularly productive between mid-September and mid-October. Sites should be scoped out during the daytime and then visited again at least one hour following dusk, using a torch to locate and identify the moths.
Sugaring is a useful technique for attracting moth species that may not be easy to catch using a moth trap. (It is also a good alternative if you don’t have access to a light trap). It involves painting a tree trunk or wooden post with a sweet sticky mixture and then going back after dark to see what has arrived. As many moth species feed on nectar, sap and honeydew, the sweet sugaring mix is particularly attractive to them. This useful guide from Butterfly Conservation includes a recipe, as well as lots of information about other methods of surveying moths without a moth trap.
How do I take part in Moth Night?
You can take part in Moth Night in any way you choose. If you have a moth trap then you can run this in your or garden or further afield. If you don’t have your own trap then you can look for moths that are attracted to your windows from the house lights, go for a walk to search local ivy blossom, or you might want to attend or organise a public event. For details of events in your area, take a look at the map on the Moth Night website.
Where and how do I submit my sightings?
Records of the moths you have seen should be submitted via the Moth Night online recording form. All of this information will be incorporated into the national dataset, helping to providing a comprehensive view of moth populations and distributions around the country. Full details and a list of FAQs about submitting your results can be viewed on the Moth Night website.

Can you recommend a moth trap?
For an introduction to the main types of moth traps and answers to our most frequently asked moth trap questions, take a look a the NHBS Guide to Moth Traps. We have also included a list here of some of our best-selling traps.
6W 12V Portable Heath Moth Trap
This small compact 6W moth trap runs from a 12 volt rechargeable battery with a minimum rating of 12Ah. The trap is lightweight and can be fully dismantled for easy transport.
Flatpack Skinner Moth Trap with Electrics
Constructed from FSC certified European birch plywood, this trap slots together easily without the need for any tools. It has a 240V lighting system fitted and includes a 25W blue black bulb.
Mobile 15W Actinic Skinner Moth Trap
This trap is particularly suitable for garden use. Easily assembled, it folds flat for storage or transportation. It is designed so you can access the catch whilst the bulb is still on.
Twin 30W Actinic Robinson Moth Trap
The Robinson is the traditional design of moth trap, and offers maxiumum catch rates and retention. This trap is particularly suited to unattended overnight operation.
This nationwide survey, launched in 2010 and conducted annually, is the world’s largest survey of butterflies; in 2016 over 36,000 people took part! The survey aims to investigate trends in butterfly and moth species and will help guide conservation efforts within the UK.
Taking part is easy – simply set a timer for 15 minutes and then count the butterflies you see during this time. Counts are best undertaken on a dry, sunny day and good places to conduct the survey are in your garden or in a local park or woodland.
If you are counting from one place, count the maximum number of each species that you can see at a single time. (This ensures that you don’t count the same butterfly more than once). If you are doing your count while walking, then simply total up the number of each species that you see during the 15 minutes. The final step is to submit your results online or via the iOS or Android app.
NHBS stocks a full range of butterfly survey equipment, including nets, binoculars, collecting pots and field guides. Need some advice? Contact our customer services team on +44 (0)1803 865913 or email email@example.com
In this brief guide we will take a look at the main types and designs of moth traps. We will also address many of our most frequently asked questions, including why you will no longer find Mercury Vapour traps for sale at nhbs.com.
Robinson Moth Traps
Robinson Traps are the preferred choice amongst many serious entomologists because they offer the highest retention rates. On a very good night you may catch in excess of 500 moths. They tend to be more expensive that other types of trap, however, and they are quite large. They also cannot be collapsed down for storage or transport. The Robinson Trap is available with twin actinic bulbs and is powered by 240V mains electricity.
Skinner Moth Traps
Skinner Moth Traps will attract a similar number of moths to Robinson Traps. However, they are less efficient at holding the catch. The main advantages of Skinner Traps are price and portability, and they also let you access your catch whilst the trap is running. Skinner Traps collapse down quickly and easily when not in use, making them very easy to store and transport. They are available with actinic electrics and can be provided with either 240V (mains powered) or 12V (battery powered) control panels. Lucent traps have a clever design with all components fitting neatly into a suitcase-style case.
Heath Moth Traps
The traditional Heath Moth Trap has a small actinic tube mounted vertically within three vanes that work together to attract and then deflect moths downwards into the holding chamber below. The traps are very lightweight and portable and are usually powered by a 12V battery, although mains powered traps are also available. Variations on the Heath Trap design include the “Plastic Bucket” model which allows the trap to be packed away and carried conveniently. Although catches from Heath Traps tend to be less than for Robinson and Skinner traps due to their lower wattage bulbs, their affordability and portability makes them a great choice for beginners or for use at remote sites.
Moth Collecting Tents
Moth Collecting Tents provide a unique alternative to traditional style moth traps and are ideal for educational use or group trapping events. They consist of a large white fabric structure which is fitted with a UV light source. Moths which are attracted by the light settle on the white fabric and can be observed or collected for study. As the collecting area is large and accessible, it is easy for many individuals to view the specimens at the same time. However, tents and sheets do not have the same retention rates as traditional box-type traps.
Moth Trapping FAQs
What kind of trap is best for garden or educational use?
The design of the Skinner Trap means that you can access the catch without having to switch off the bulb. This is particularly useful if you are looking at your catch over the course of the evening, rather than leaving the trap all night and returning to it in the morning. Skinner Traps also have the added benefit of collapsing down, making them easier to store.
Which trap is best for unattended trapping?
The Robinson Trap is the only trap that will retain the whole catch after dawn. Some moths will escape from other trap designs.
Which trap is most portable?
Heath Traps are the smallest and easiest to transport. They can also run off a 12V battery, allowing them to be used in remote sites. The Safari and Ranger Moth Traps are the smallest and lightest traps we sell, so are ideal for travelling.
Why can I no longer find Mercury Vapour traps on your website?
Mercury Vapour bulbs have recently been phased out as part of the Restriction of Hazardous Substances Directive. Therefore, we have removed the traps from our range and are now focusing on actinic replacements. If you have a Mercury Vapour trap and would like to convert it to run with actinic electrics, please get in touch with us to have a chat about this.
What are actinic bulbs?
Actinic bulbs produce a small amount of UV light alongside the visible light which makes them more “attractive” to moths. They are not as bright as Mercury Vapour bulbs but because they don’t get as hot they are much safer to use, particularly for public and attended trapping events. They are also much less of a disturbance to neighbours if you are using the trap in your garden.
What is the difference in catch rates between the different traps?
The Robinson Trap and Skinner Trap will attract a similar number of moths but the Robinson has the highest retention rate of the two. Heath Traps will retain fewer moths but will still attract the same range of species. You can therefore obtain similar results trapping for a longer period or over several nights in the same area.
The order Orthoptera consists of the grasshoppers and crickets. Although most suited to warmer climates where they are incredibly diverse, in Britain we have 27 native species, as well as a number of non-native, naturalised species. From a very young age we are aware of these beautiful creatures as the sounds they produce fill our countryside with noise.
The characteristic Orthoptera song or “stridulation” is produced either by rubbing the wings together (observed in most of the grasshoppers) or by rubbing a hind leg against a wing (a method used by most crickets). The sound produced is an important part of the courtship ritual and is also used for other types of communication. As the sound created by different species varies significantly, studying these calls is an excellent way of surveying Orthoptera, and is helpful for finding individuals which can then be identified visually.
Stridulation produces a sound which covers a variety of frequencies – the sound made by grasshoppers is usually audible, but many species of cricket produce a higher ultrasonic frequency which cannot be heard by most humans. The use of a bat detector to listen to these higher frequency songs is an excellent way to listen to those species that we would not ordinarily be able to hear, such as the Speckled Bush Cricket. It also allows us to increase the range at which we can hear the audible ones. Bat detectors are also of use to older surveyors, whose ability to hear higher frequencies has naturally declined.
A simple heterodyne detector is perfect for listening to grasshoppers and crickets – one such as the Magenta Bat 4 or the Batbox IIID is ideal as it allows you to tune it to a specific frequency (as opposed to some of the more “intelligent” detectors which will alter it for you). The detector should be set to a frequency of 35-40kHz then all you need to do is sweep it around in different directions until you pick up your subject. It is best to stand in one place while surveying as the noise produced by your footsteps and clothes moving will produce background ultrasound noise which can confuse what you are hearing. The best days for surveying are warm and sunny; crickets are generally crepuscular (active during twilight) whilst grasshoppers are usually active throughout the day.
Congratulations on the book and on publishing the first regional distribution atlas for dragonflies in Sweden. What is your background in natural history? Have you always been interested in dragonflies?
Thank you very much! I am a biologist and work since 2005 at the department of Nature Conservation at the County Administrative Board of Östergötland, mainly with action plans for threatened species. I have always been interested by natural history, and as a kid I liked to collect larvae of dragonflies, stoneflies, mayflies and other limnic insects. However, my interest for imago dragonflies and identification of species started during my biology studies, about 2002-2003.
For those who may not be familiar with the natural history of Sweden, what sort of place is Östergötland in terms of biodiversity and landscape?
Östergötland is situated in south east Sweden and covers 14,500 km sq. It is situated in the boreonemoral vegetation zone and can be divided into four natural geographic regions: the southern woodlands, the plains, the archipelago, and the northern woodlands. The woodlands and the archipelago mainly consist of coniferous forests, while the plains mainly consists of intensively cultivated agricultural land. The woodlands have great numbers of lakes and mires, while the plains are very poor in water. The main part of Östergötland is lowlands, but in the southern woodlands there are considerable areas above 200 m.a.s.l. The bedrock in the county is mainly acid but in the western part of the plains there is an area of Cambro-silurian calcareous rock. During the last glaciation, calcareous material was dispersed southwards, resulting in calcareous soils in some parts of the southern woodlands with granite bedrock. As a consequence of bedrock and soils you find mainly oligotrophic and dystrophic waters in the northern woodlands, eutrophic waters in the plains, and a mix of oligotrophic, dystrophic and mesotrophic in the southern woodlands. Östergötland, along with other southeastern regions, is one of the most species-rich regions in Sweden considering invertebrates due to its relatively warm and dry summers. It is well known for its considerable areas with hollow oaks and the saprolyxic fauna and flora associated with them.
How do you co-ordinate a project like this, with 150 volunteers over the course of five years (2008-2012), and what were some of the highs and lows?
It worked out very well since all was based on voluntarism. After getting initial information about surveying and identifying dragonflies, the participants could work quite independently. Most of the communication with the participants was made through e-mail. In addition, several activities were organized: kick-offs every spring, survey courses and excursions during summer, and reporting courses during fall. Many of the participants had no experience of surveying dragonflies before, and the fact that we managed to get so many volunteer amateurs out surveying dragonflies was one of the highlights of the project. Furthermore, the participants were a heterogenous group in terms of age and gender, and not only older men which is common in entomological contexts.
In the study you make comparisons with 10 other regions in Europe. What conclusions have you been able to draw through these comparisons?
Yes, I compare Östergötland with some other European regions where dragonfly surveys have been performed. Most of the regions have more species than Östergötland because they are situated south of Östergötland. On the other hand, Östergötland has two species which generally are missing in the other regions: Coenagrion johanssoni and Aeshna serrata. When comparing the species the regions have in common, the frequency for some species differs a lot between Östergötland and the other regions. Östergötland is distinguished by the fact that species classified as red-listed and/or decreasing in Europe occur more frequently in Östergötland than in most of the other regions. Particularly Coenagrion armatum and Leucorrhinia caudalis can be pointed out as much more common in Östergötland. Thus, Östergötland has both a national and international responsibility for these species, together with A. serrata, Aeshna viridis and Nehalennia speciosa. The reason for this is that important habitats for these species, such as bog ponds and mesotrophic lakes are naturally more common in Sweden, and that the exploitation of waters in Sweden has not been as severe as in central Europe.
What were some of the other significant findings of the project?
Probably because of global warming there is an ongoing change in the European dragonfly fauna where several southern species have expanded rapidly northwards and some northern species have retreated. In Östergötland the establishment of Lestes virens and Ischnura pumilio has been documented during the survey. L. virens was observed for the first time in the county in 2005 and, during the period 2008-2012, was found at several new localities every year. I. pumilio was first noted for the Östergötland in 2012.
And what is next for you and for the Östergötlands Entomological Society?
This year I have got the assignment to co-ordinate Sweden’s monitoring of the dragonflies species listed in the EU’s habitat directive. It will be very nice to work professionally with dragonflies and I have learned a lot about these species and dragonfly monitoring during the survey in Östergötland. I started this work last week with a field study of Ophiogomphus cecilia, a species only occurring in some few unregulated rivers in the very far north of Sweden. Concerning the Entomological Society in Östergötland, we have discussed the possibility of starting up another voluntary survey of some other easy identified insect group, e.g. shield bugs or grasshoppers, but nothing is ready to start yet.
BugDorm have been supplying equipment for entomological research and teaching since they were established in 1995. Their products have become firm favourites with both professional and amateur entomologists and they are continually being developed to address the challenges encountered by field and lab workers everywhere. NHBS is proud to be a distributor of the BugDorm range.
For breeding and rearing insects, the BugDorm range of cages and tents offer a solution for every situation. Available in a wide range of sizes and mesh apertures, most have both entrance sleeves and zippered doors for convenient access. All pack flat for storage and transport. For rearing and studying insects in situ, insect rearing sleeves and bags allow you to contain leaves and branches within a temporary enclosure.
The innovative Slam Traps work on the same principle as the malaise traps, but can also be strung in a vertical chain to sample at different heights in the canopy. When used with the bottom collector (available separately), they will also collect insects such as beetles, that drop when they hit the trap. A four-headed version allows you to study migration patterns by collecting insects entering each of the four quadrants into separate collecting bottles.
The BugDorm range of insect net sets let you create your own net from a selection of frames, bags and handles. Net frames are collapsible and handles are telescopic with the longest options extending up to 530cm in length; ideal for sampling in the canopy.
