I believe this is in genus Temnostoma, is that correct? According to nearctica.com, the Nearctic species of Temnostoma are: T. acrum, T. alternans, T. balyras, T. barberi, T. daochus, T. excentrica, T. obscurum, T. trifasciatum, T. venustum, and T. vespiformis. Can anyone shed some light on the species ID of this fly? Forest near a small stream, 7 June 2007, West Virginia USA. Length 10-11 mm. Thanks in advance for any help!

Here's a view of the fly's "face."

No, it's not T. bombylans, because this is a species from the Nearctic, and there is no bombylans there. There are several species who looks like this: balyras, barberi, obscurum and trifasciatum. When I interpret the picture right, it seems that tergite 5 is extensively yellow pilose, and of these four species only T. balyras has that feature. So, my idea would be a male of Temnostoma balyras!  Greetings Greetings, Gerard Pennards |

Amalia, Gerard, Thanks for commenting. I'm posting another photo that shows better the yellow pilose area Gerard mentioned. The range for T. balyras seems to match, living in the eastern United States and Canada. Thanks again for your help! --Stephen Stephen Cresswell www.americaninsects.net |
