A very useful, and convenient, character for identifying female Chrysops spp. is the absence (top image C. calvus)) or presence (bottom C. mitis) of a yellow pollinose stripe on the clypeus. These character states readily divide the North American spp. into 2 more manageable groupings.

As nicely illustrated.

In the Old World, unfortunately, the majority is of the lower type.

For Idiohelina, 3 Malloch's papers, Exotic Muscaridae III, XV, and XXXV

Species with mouth parts that appear to be 'similar', like Sargus, do feed on honeydew. I have never seen Hermetia in nature...

Thanks Paul, some sites report that it don't have functional mouth part, other sites say it feed nectar, some publications say it "probably" feed nectar and it's a pollinator.

18.09.15 11:57
Sounds like it might be. Do sites that 'say not' state that they do feed or don't they mention anything?

14.09.15 20:42
Question: is it true that the Hermetia illucens don't have functional mouth part? Some sites say yes and some other say not. It's a bit confused. Thanks Smile

looks like it! Grrrr.

Fauna Europaea unavailable again!?

28.08.15 22:58
I'm searching a Muscidae pdf for the New Zealand fauna (Idiohelina genus), I hope someone can help me with a link, thanks in advance!
