An extremely close-up photo of a little beetle with a black rear, a shiny read upper abdomen, and a reddish thorax and head, with moderately long antennae. It is walking around on decayed wood.
I love finding these weird cool little ant-loving beetles (Pselaphinae).

And another little Pselaphinae from my most recent foray into the Lincolnshire Wolds, Bibloporus minutus, a little chunk at 1.3mm, the rarest of the two British species, bicolor was present as well. Slightly lighter in colour than normal, probably teneral. #Staphylinidae #Pselaphinae #Coleoptera
Euplectus infirmus, 1.3mm. Lincolnshire Wolds yesterday. #Staphylinidae #Pselaphinae #Euplectini up there as one of my favourite families.
Yes I know I’ve put pictures up of this beetle before, it’s not rare, I’ve found it on multiple occasions in several English counties. It is however my type of beetle. Pselaphis heisei, Cumbrian wet meadow. #Pselaphinae #Coleoptera
Tychus niger, improved pasture left ungrazed, Derbyshire. Pretty common but never easy to find in numbers. #Pselaphinae #Staphylinidae #Coleoptera
A #pselaphinae caught in an ethanol trap hanging over a beaver pond. Do any #coleoptera folks have any suggestions for narrowing it down ? www.inaturalist.org/observations...
