Robber Fly - Laphria sericea

Robber Fly - Laphria sericea
Boxborough, Middlesex County, Massachusetts, USA
June 16, 2005
Size: about 12mm

Laphria serciea/aktis
Looks very like Laphria serciea/aktis, e.g., see Giff Beaton, Herschel Raney. The latter page says: " L. aktis has an all dark beard". See also:



Note also photo of L. aktis--Insects of Cedar Creek.

Golden robbers
This aktis and sericea pair seem to lock the wings open at landing much more often than the other species. And note that Bullington does not include these species in his online keys because he felt they should not be in the genus Laphria at all. L. aktis shoud be much less common in the NE but it may not have been studied that much. I don't recall if Michael Thomas has any specimens of L aktis from NH and Vermont. I will check with him. Note that L. janus is golden abdomened as well but has less of a golden cover on the thoracic shield.

By the way, damn fine shot Tom.

 
Laphria serciea/aktis
I added another shot showing the face, would that help in the identification? There were 4 of these flying in the same woods.
Thanks again for the help.
