Somerset trip: Small fly with yellow body.
(Considered Turnip sawfly but it doesn't seem quite right.)
No interactions present.
Thank you for the ID. I did a NBN Gateway search but it changed the name to Sciara hemerobioides. Looks like the same fly.
Yes, used to be hemerobioides, but now thomae.

Is this the only species that has the bright yellow abdomen? I've seen flies like this several times but have never known whether it is safe to record them as S. thomae.

According to the checklist on Dipterists Forum, there are 7 Sciara. Interestingly, it has hemerobioides as the current name, rather than thomae. For some reason, I thought it had changed back? Roger Morris identified one on here as thomae, recently, and when I checked in Freeman's RES Sciarid guide, I got the impression that thomae was the only possibility (not altogether clear, though, as the key does not concentrate on colour).
