New Wasp for me (Specidae?) Calhoun County - Physocephala floridana - male

New Wasp for me (Specidae?) Calhoun County - Physocephala floridana - Male
Blountstown, Fl in the Panhandle, Calhoun County, Florida, USA
March 20, 2014
Size: 15mm +/-
New wasp for nectaring in profusely blooming Prunus angustifolia (Chickasaw Plum) in bright sunshine, 70 degrees. I checked Sphex and Isodontia. No really good matches. Note the white blaze on tibia of first two legs. I don't know how to do gender on this guy. Antenna not crooked and the abdomen has 5-6 segements (do you count the "thread waist"?)

Regarding Travis's question on gender here
Females in subfamily Conopinae (i.e. Physocephala and Physoconops...of which Florida has more species than any other state in the US) can be distinguished by a large bump (the "theca") protruding below the 5th abdominal sternite. This individual lacks a theca, and is a male.

Great find & interesting color form. This is my favorite Physocephala species :-)

Physocephala- Calhoun County
Wow! Thanks. I never suspected. Beautiful insect. I see the haltars (sp?) now. And I see that it is a male per comments elsewhere. Fool me once... And a week ago I posted a moth on here that was a fly... sigh... but onward.

It's a fly! I suspect Physocephala floridana.
