What an absolute stunner, Lomechusa emarginata, a myrmecophile that migrates between Myrmica ants in the winter to Formica sp. in the spring. This one in Myrmica nest in dry cow dung. #Staphylinidae #Coleoptera #Nottinghamshire

A rove beetle standing on a pale rock. It’s a slender, dark reddish brown beetle that looks like it has been assembled from a collection of geometric shapes.

I spotted this lovely little rove beetle on a rock in the Peak District. Tentatively keyed out to Othius, with Othius angustus suggested on a Facebook group.

A small black beetle sits on the light green underside of a leaf. It is shiny with small punctures and hairs, and has a tapered abdomen. It's elytra, or wing cover, are short like many other rove beetles.

A small black beetle sits on the light green underside of a leaf, investigating a piece of debris. It is facing the camera with its abdomen pointed up and over itself. The beetle is shiny with small punctures and hairs, and has a tapered abdomen.

A small black beetle sits on the light green underside of a leaf, investigating a piece of debris. It is facing to the right with its abdomen pointed up and over itself. The beetle is shiny with small punctures and hairs, and has a tapered abdomen.

A small black beetle sits on the dark green upper side of a leaf. It is shiny with small punctures and hairs, and has a tapered abdomen. It's elytra, or wing cover, are short like many other rove beetles.

I'm rolling out some older pics I never got around to processing.

Here's one of the smallest (~1mm) rove beetles I've seen. This cutie was found on a rose leaf, associated with its prey, spider mites. I ❤️ how they hold their abdomen up 🥹

Gyrophaena, they all look pretty much the same until you dissect out the median lobes. I don’t much bother with a key, just find a male and whip its bits out. Here’s one from Gyrophaena fasciata. #Staphylinidae #Coleoptera #Beetle
