A metallic Blue Ground Beetle with long legs and textured wing cases crawling across bright green moss.

Rotting wood partially covered by vivid green moss.

A dense, moss‑covered woodland with twisted, lichen‑clad tree branches and large mossy boulders, creating a lush, damp temperate rainforest scene.

A close-up of a metallic Blue Ground Beetle with large pincers at the front.

Meet one of the UK’s rarest beetles that has been found in some temperate rainforests in the South West! 💙🪲

It loves damp woodlands, with lots of veteran trees and deadwood, which provide the sheltered hiding places it depends on.

Are you one of the lucky few to have seen one?

For @ashwhiffin.bsky.social's #BlueBugs, here is a gorgeous male Adonis Blue I had the good fortune to meet at Folkestone Warren last summer. 💙

Every year I try to repurpose #BlueMonday (which we all know is a load of 💩) and advocate for #insects by showcasing some beautiful BLUE BUGS!

Cool idea! The perks of having a brother with a 3D printer 😁

That’s so cool that you tried it Steph! 😊 Really keen to hear any feedback so we can improve it.

😁 thank YOU! I’m so glad you tried it! Do send any feedback our way.

I’m sorry BlueSky, I have been neglecting you.

Sadly not able to make it this year! Got a clash 🙁

Entoblock step An improved pinning block for entomological collections. It has five steps at different heights for quick and accurate label setting. The steps are visible from both sides, making it suitable for lef...

Steven Hammer, one of our regular collection users, co-developed a new #insect pinning block, with staff and volunteers from the museum.

It’s 3D-printed and open source, so you can try it for yourself:

Two mahogany cabinets, 20 drawers each with 1,675 insects. Donated by Riker's grandchild Marcia Rissland in 2000

Original patent for the Riker mount.

Close up of the hardware holding the glass on a Riker mounted butterfly and cabinet drawer mechanism.

An example of Riker mounted moths at different life stages.

Original Riker mounts by inventor Clarence Riker held at @denvermuseumns.bsky.social , presented by Genevieve Anderegg! 😍

The cabinets are just as intricate as the insects held within!Though lacking in collection data, lots of educational & natural history research value once imaged!

We're at #ECN2025 in Portland, Oregon!

We're passionate about entomological collections, which is why we published some of last year's ECN in a special topical collection: nhcm.pensoft.net/topical_coll...

Check out the @pensoft.net stand for our latest news!

A few panels from the coloring guide: a scorpion, an isopod, and a tachinid fly (along with their info).

It's almost the weekend! 🥳

If you're looking for something for you and/or your kids to do, I've recently re-uploaded my arthropod coloring guide 🎨

Please feel free to share, print, and [definitely] have fun with it!!!

Cole & Conner at one of their events, teaching children about insects.

Since 2023, this pair have organised over 15 public events & reached thousands of attendees!

They create their own specimen displays & use these in combination with live insects to explore insect biodiversity & teach basics collection techniques.

Incredible efforts from this young duo! 👏 [3/3]

Connor & Cole are two friends on a mission to engage children with insects.

What started out as a simple idea has grown into one of the leading youth-focused entomology programs in Southern California, and the first youth division of the Lorquin Entomological Society. [2/3]

If you attended the @entcollnet.bsky.social meeting last year in Phoenix, you may have met some of our youngest attendees, Connor Hsu & Cole Crammer. Here they are with @drfirefly.bsky.social!

They’re now in 11th grade and this year they’re back to deliver their first ever ECN talk! [1/3]

An utterly adorable illustration of a cartoon Rain beetle, complete with an orange umbrella and yellow rain boots.

🧡 @americanbeetles.bsky.social has really delivered again, with stickers for our meeting.

Behold… the most adorable Rain beetle you have ever seen! 😍

This was such a fascinating and uplifting story of the evolution of a collection. What Chris has managed to achieve for the Oregon State Arthropod Collection is remarkable. 🥹👏 #ECN2025

Satisfying but intimidating layout of disassembled imaging system. It’s Linux for photography

Next year we will have speed trials for assembling Chris Wirth’s portable focus stacking camera system

Super useful tips & tricks for insect specimen imaging from @andrewjohnston.bsky.social! He shares how to build an affordable focus stacking system on your own.
