Novices often confuse them with syrphids because they behave similarly and sit on flowers a lot. They are still tachinids though because they are all parasitoids; they are calyptrate flies; and they (99%!) have a strong subscutellum.

Again my thanks, Chris :-) Pierre OGER 4217 H?ron (BELGIUM)

Member Location: Belgium (Héron) Posts: 150 Joined: 11.08.07	Thanks Gerard I read that it is in UK endangered... and not known in Belgium : so I don't think I will encounter it. But that's true, it seems difficult to believe that it is a syrphid Pierre OGER 4217 H?ron (BELGIUM)

And in this genus also the name reflects this : Gymnosoma means "naked body" (or abdomen).
