Nomada? - Sphecomyia vittata - male - female

Nomada? - Sphecomyia vittata - Male Female
Fairfield, Wayne County, Illinois, USA
April 28, 2006
Found this pair in my wood pile. Based on last weeks discussion I'm suspecting Nomada - but these are different than last week's individual and about a hundred miles further north.

Sphecomyia vittata
These are awesome pictures of Sphecomyia vittata! They are syrphid flies which mimic very successful wasps....Great pictures of these beautiful flies.

Thanks, guys and gals
My friend, who was cutting wood with me thought I was going bonkers when I ran to get my camara shouting "Don't let them get away!" Like, what could he do? Anyhow, life is grand.

Polybiomyia
My guess is this is Polybiomyia. They are supposed to resemble the Polybia wasps. I think this qualifies. Highly unusual antenna in the syrphid group. There may be more than one species in Illinois but I think they are mostly southwestern if this is Poly. Only P. pedicellata occurred in Weems collections in the SE.

Syrphidae
Maybe Sphecomyia - possibly vittata? Just a guess.

 
Sphec
Nice guess. Martin agrees. Fine shots now linked to my key.

These look like flies
with one pair of wings - Diptera - and a pair of halteres. Will check for similar images.

 
Wasp or Fly
Whatever they are the sure are beautiful. Nice shot.
