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.

Hello, Sericomyia-Arctoph
ila... this synonymy is based on Nearctic material only. Although very respected authors, I think it is not wise to follow this synonymy without studying palearctic Arctophila

Approaching 2/3s, which I consider a very good result already. But there is room for improvement. Wink

28.11.16 17:26
so, Paul, almost 50% of the costs is not covered yet.

28.11.16 13:40
Thanks Theo! So it "should" be Sericomyia (Arctophila) bombiformis.

28.11.16 11:45
It is a matter of opinion. Some (modern) authors consider Arctophila no longer valid at genus level.

25.11.16 07:51
Hello! Can someone please tell me what's the actual name for Arctophila bombiforme? There are: Sericomyia (Arctophila) bombiformis, Sericomyia bombiformis and Arctophila bombiforme. Thanks Smile

Paul I submitted another (better) photo of Madiza pachymera for the gallery

21.11.16 11:49
Thanks Paul

21.11.16 10:36
FYI: The name can also refer to the Dipteran family Clusiidae, named after the genus Heteroneura (= Clusiodes).

Thanks John that's looks good
