I saw several of these syrphids (I think) taking nectar in the Lower Rio Grande Valley, but this was one of the few that held still, on a cloudy, cool day. Size estimated. Thanks for help with identification--see comments. Note the prominent yellowish
halteres.
This photograph was taken during a field trip as part of the 2006
Texas Butterfly Festival in Mission, Texas. This was the odonate trip led by
Josh Rose and
Bob Behrstock.
