Species ID - Pryeria sinica - male - female

Species ID - Pryeria sinica - Male Female
Anne Arundel County, Maryland, USA
October 22, 2009
Size: Approx. 1"
Swarmed group were observed in a mating/ovipositing frenzy that went on for a couple of days. Bodies were hairy, similar to that of a bumble bee, wings were transparent, antenna of females were round and clear of any appendages while those of the males had "palm-frond" shaped appendages. Host plant was a "Manhattan" Euonymus. As of 10/31/2009. the eggs were unhatched and there have been three female insects that have remained with the eggs.

Moved from ID Request.

Makes us think of
Pryeria sinica - Hodges#4639.1, in the guide here. As you can see from the comments on this image
, it had been restricted to Anne Arundel County. Apparently they swarmed on Oct 26 in 2008. We have some images on BugGuide from Fairfax Co, Virginia

Additional Information
These insects are swarming again (November 1 & 2) but in much smaller numbers than before. I have observed no mating activity...just somewhat timid approaches to each other when one alights. They are still partial to the Euonymus. Their flight characteristics remind one of the flight of the lightning bug...somewhat slow, erratic and oblivious to the presence of humans.
