Leicestershire entomology reaches the end of (another) era

Leicestershire and Rutland Entomological Society logo

Yesterday was a sad day for me personally, but from a wider perspective...

After 38 years, Leicestershire and Rutland Entomological Society (LRES) has scaled back operations due to falling participation and an elderly demographic. It's not completely gone, and the intention is that arrangements will be made for publications to continue (the plan is that the Natural History Section of the Leicester Lit & Phil Society will pick up the remaining activity of LRES, notably publications), but there won't be any more dedicated entomology meetings. We're not, of course, the first or the only society this has happened to. 

A VC55 entomology society has blinked into and out of existence and number of times, first as an offshoot of the Zoology Section of Leicester Literary and Philosophical Society. In the second half of the 19th century Leicester was an entomological powerhouse. Before a dedicated society existed, entomology in the region was driven by the "Lit & Phil", founded in 1835. Perhaps the most famous name associated with this is Henry Walter Bates, the Leicester lad and explorer who discovered "Batesian mimicry." In the momentous year 1844–1845, a young Alfred Russel Wallace moved to Leicester to take up a position as a master at the Collegiate School, teaching drafting, surveying, and English. While he was already interested in nature, he hadn't yet found his specific calling. Everything changed in Leicester. Here, Wallace met Bates, a local man who worked in his family’s hosiery business but spent every spare second obsessed with entomology, spending his limited free time collecting beetles in Bradgate Park and Charnwood Forest. Their friendship quickly turned into a professional partnership. By 1847, Wallace was bored with teaching and proposed a radical plan: they should travel to the Amazon rainforest to collect specimens and sell them to museums and collectors back in London. They left for Pará (now Belém), Brazil, in 1848. While they eventually split up to cover more ground, their time in Leicester remained the foundation of their careers. Frederick Bates, younger brother of Henry Walter Bates, began publishing in the Transactions of the Leicester Literary and Philosophical Society from the 1850s. In the late 19th century, figures like William Armston Vice and Frank Bouskell pushed for a specialized entomological section. For a time, a "Leicester Entomological Club" operated within the Lit & Phil, eventually evolving into Section F (Entomology) by the 1880s, producing the first comprehensive local checklists for the Victoria County History (1907). The Entomology Section ceased to operate during the 1939-45 World War and was not restarted after the War. 

 The Great Hiatus and the 1988 Rebirth

Following the 1939-45 World War, there was no formal entomology society. Naturalists of all shades typically met at the Leicester Museum, which acted as a de facto hub. Notable Leicestershire entomologists tended to interact directly with national entomology organizations. The modern society was born from a desire for a more focused, member-driven group when on June 8th 1988, a meeting was held at the University of Leicester to discuss forming a society. On September 5, 1988, the Leicestershire Entomological Society (LES) held its first official meeting at the New Walk Museum. A small number of founder members still remain. The society has always covered Watsonian Vice-County 55 (VC55), which encompasses both Leicestershire and Rutland. To formally recognize this, the society officially rebranded as the Leicestershire & Rutland Entomological Society (LRES) in 2022.

And now, it's over again - for now. Perhaps the "Leicestershire Entomological Club" will naturally re-emerge. Whether we blame Covid, social media, or Margaret "there is no such thing as society" Thatcher, I'm not happy this has happened on my watch, but the cyclic nature of Leicestershire entomology allows me to take comfort in the philosophy of Heraclitus - 

No man ever steps in the same river twice, for it's not the same river and he's not the same man.

Entomology Update - February 2026

February was a varied month, spring-like at times but mostly wet. I didn't get out much but made some interesting finds when I did. 


I try and stay well away from culture wars, but it recently came to my attention that there is some new terminology I should be aware of.  

OM System has launched a new version of the TG-7 camera for microscope use.

Transparent card protector sleeves (widely available online) are useful for harmlessly restraining insects for photography, including under the microscope.


Notable Finds
The observant may notice a theme to this month's Notable Finds. I haven't had chance to write about this yet but will do so next month. 

Cyrtogaster vulgaris, first record for VC55
Callitula bicolor, first record for VC55
Delphacodes venosus, second record for VC55
Epiclerus panyas, first records for VC55
Ooctonus vulgatus, first record for VC55
Microterys tricoloricornis, first record for VC55

Card Protector Sleeves

Transparent card protector sleeves (widely available online) are useful for harmlessly restraining insects for photography, including under the microscope. They're a little too shiny to be perfect so you need to arrange the lighting to avoid surface reflection. They are earier toi use in the field than the alternative - floating frames

TG Camera News

TG7 Ind

The PetaPixel website reports that OM System has launched a new version of the TG-7 Kit made for microscopes. The TG-7 Industry is a slightly modified TG-7 but the NY-TGV Super Adapter Kit is of most interest. I can't see any reason why this couldn't be used with any TG5, 6 or 7 camera. 

I don't think this is the best or most cost-effective solution for a microscope camera, but if you already have the TG5, 6 or 7 the adapter kit might be worth checking. 

The kit will be available in a few months time, UK pricing not available yet, but it is aimed at industrial users (who clearly have deep pockets).

Culture Wars - Scientists versus Citizens

I try and stay well away from culture wars, but it recently came to my attention that there is some new terminology I should be aware of:

Citizen Science - typically top-down. Usually initiated and managed by professional scientists or by institutions. To collect large amounts of data labour is "crowdsourced" to the public.

Community Science - typically bottom-up. Usually initiated by a group of people who have a specific concern about their environment. The community are co-creators and owners of the research and frame the question(s), design the study(ies), and interpret the results.

Rule of thumb: If a project asks you to "help us help science," it’s likely citizen science. If it asks "how can science help us?" it’s likely community science.

Entomology Update - January 2026

After a freezing start, January was mostly ... wet, limiting entomology opportunities.

Oligometry

Peritrechus geniculatus

In Peritrechus, the structure of the antennae is an important diagnostic character. In Peritrechus geniculatus, ant3 is as thick or thicker than ant1, whereas in the other very similar species it is thinner. This recent specimen was missing the left ant4 but still identifiable as P. geniculatus. Then Jim Flanagan pointed out something odd to me. Maybe the left ant4 never got lost - it just didn't grow? The key is that the left ant2 is longer than the right - this is called oligometry and is frequent in Lygaeidae. Oligometry usually results in one of the antennae having three segments (it can also affect both antennae and then it is known as bilateral oligometry). It is thought to be caused during late development phase but precise reasons behind this deformation are not well known.

The Mysteries of the Metapleuron

Nysius senecionis

I've always found Nysius to be a difficult genus to identify, apart from the obviously hairy N. huttoni. I turned up a few at the weekend but this time I used the key published by by Dolling, Het News, Issue 2, Autumn 2003. This turned out to be much easier than the other keys, and in the blink of an eye I had this one down to a species pair - N. graminicola vs. N. senecionis. The hind tarsi indicated which of these two it was, but to confirm I had to check the metapleuron, which confirmed that this was Nysius senecionis

Nysius senecionis metapleuron

Which raises the question - what the heck is a metapleuron? In Nysius the metapleuron is the lateral sclerite of the third thoracic segment and is the primary platform for the metathoracic scent gland (MTG) system. It consists of:
  • The ostiole: an opening on the metapleuron through which the MTG reservoir empties its contents.
  • The peritreme: a specialized cuticular structure (often shaped like an auricle or spout) that surrounds the ostiole. This directs the liquid secretion away from the body and onto the evaporatorium.
  • The evaporatorium (or matt area): a distinct, non-glossy region of the metapleuron characterized by a highly micro-sculptured, "mushroom-like" or reticulated cuticle which increases the surface area significantly, allowing the defensive fluid to spread rapidly and evaporate (volatilize) almost instantly. This creates a "scent cloud" that deters predators before they can make physical contact.
The most important physiological role of the metapleuron is the dispersal of repellent defence chemicals. An additional role is in pheromone communication, acting as a broadcast structure for alarm, aggregation and sex pheromones. The specialized cuticle of the metapleuron evaporative area also prevents defensive secretions from being absorbed back into the insect's own underlying tissues.

I don't know about you, but it seems like a metapleuron might come in quite useful.

An odd spot

7 Spot Ladybirds

I made my first ladybird records of the year yesterday. Since December, through all the rain, frost and snow of January, through Storm Gorblimey, these two 7 Spot Ladybirds, Coccinella septempunctata, (which had a good year), had been huddled up on a Yew planted a few years ago precisely to give overwintering shelter for invertebrates. But rather than seeking shelter they were clamped to the tip of a branch in the most exposed spot possible. I was starting to wonder if they were alive, or semi-alive (parasitised), but when I took their photo (without touching or disturbing them as far as possible), they wandered off in a huff and settled down again a few inches away. 

In the afternoon, clearing out the garden nestboxes, I found a 2 Spot Ladybird safe and warm in a cozy woodcrete winter home. Sadly, I did have to evict this one in order to clean out the box, but yesterday was warmer so it will be fine.
