Would this be a Sphaeroceridae? Photographed yesterday in woodland near Rome, about 5 mm long.
Thanks, Sarah.

Alas, no, this is
Calliopum of the Lauxaniidae.

Hint:;) Sphaeroceridae which are often seen on dung are very active flies which disperse quickly when disturbed as Phoridae do. The wing venation is very different from Phoridae however.Also in Sphaeroceridae the hind metatarsus (basal tarsal joint) is usually very short and often dilated.Compare this lauxaniid with the gallery pics of Sphaeroceridae and look at the Phorid pics for the wing venation differences.Once Sphaeroceridae are recognized they are easy to place in the correct family:p. Dtermination is more difficult but the wing venation pics in Seguy's Faune de France volume are a real help.

Thanks Robert, when I get a moment later on I'll do some homework in the gallery... which is really getting to be an amazing resource. Sarah
