Field work half-time for #BEN_EAF! ⛰️

We took small and larger soil samples from whom hashtag#SoilFauna will be heat-extracted in the soil lab at the Aberdeen campus of the #JamesHuttonInstitute. This is mainly springtails (#Collembola), mites (#Acari), and hopeful more small critters!

Further, we did also collect the soil fauna from the pitfall traps: mainly ground beetles (#Carabidae), wolf spiders (#Lycosidae), and harvestmen (#Phalangiidae). 🕷️🪲

Thanks again to Andrea Britton and Debbie Fielding for the help in the field work!

Say hello to this Brachinus bombardier beetle from Arizona. So-named because it creates a hot, aimable explosion out of its butt when disturbed. I did not disturb it.

Cicindela sylvicola Dejean, 1822

Specimen was captured in July 1996 in the Ardennes region, France.

I've used the focus-stack technique, DIY hardware only (a Raspberry HQ cam controlled by a Raspberry Pi 3, an old Pentax-m 50mm f1.7 lens, some extension tubes, and a $30 linear rail from Aliexpress)

I swear this is a real beetle and not AI generated.

I'm guessing this little ground beetle is Notiobia. But there are an awful lot of nearly identical genera. Texas.

When both presence and absence of a species are meaningful, it is a bioindicator. #Carabidae are such species. So let's talk for a moment about about those, which have been found missing from my #forest.

Carabus auronitens F. a locally widespread forest-core species. This means, it can't cross gaps such as roads or wide forest alleys. It ventures into edges in case of moths outburst.

Despite its requirements for old trees and dead wood are met here, none was seen in 6y. Why?

Yeah. I know. I'm always talking about Carabus nemoralis Müller (Coleoptera #Carabidae) these days. Even to me it sounds unusual. I never saw that species so often. Ordinarily it uses my #forest as a winter refuge and forages there only at both ends of vegetation season. But this foraging pattern changed this year. It has been recorded continuously past the end of winter until now. And this is bad. Here is why:
