This is probably Sturmia bella? Male specimen? There is only few and rather old records from Finland at all! Can anyone confirm this ID or give some help? This emerged from Araschnia levana pupae. Not straight, but probably first emerged fly-larva from butterfly-pupae and then this emerged from reddish-brown pupae on other side tank. Butterfly larvaes collected from nettle (Urtica dioica) in my backyard garden 19.8.2010 Place: Fennia, Nylandia, Siuntio (southern Finland) Fly with naked (not hairy) eyes, overall lenght 7.0 mm. Is there mysticious "Sturmia-flecks" visible in abdomen image? ("Male: Tergit 4 ventral oder an der seite mit einem Sturmia-fleck".)

The head is not developed completely, so it looks a bit strange, but it seems to be OK. The host is typical, so that is OK as well. THe subapical scutellar bristles are set wide apart (as it should be in Sturmia) You might check: * palpus black * 4 sternopleural bristles. Theo |

Wow - looks like it flew into a wall!  It's got all the parts to say that it is Sturmia ... but it looks completely wrong, in the over all shape

Thank you very much for determination, Theo & Chris and also Kaj Winqvist from Finland. (He advise me to ask help here from Tachnid-specialists) This is rather remarkable record from Finland! Last seen 1940 (over 70 years ago) So it was so important to me to get right ID for this species. Now I can save record to our database. (maybe without gender, male/female?)
