Bee Fly? - Anthrax georgicus

Bee Fly? - Anthrax georgicus
Lakeland Highlands Scrub park, Polk County, Florida, USA
March 25, 2012
All I can come up with is Black Horse Fly (Tabanus atratus), but the venation of the wings does not match the references I have. Fly sat still on a dead leaf while I took the pictures. Scrub habitat. Thanks for any help.

I'm pretty sure this is the dark-winged Florida form of A. georgicus.

Moved from Bee Flies.

 
Doesn't match this


Are there darker and entirely dark forms in Florida?

 
Anthrax georgicus
The dark winged form apparently grades into the normal forms, so there should be a full range in between. Only the females have entirely dark wings, the males should have at least some clear areas along the trailing edge (this and the linked image are both of females).

 
I don't know the answer to yo
I don't know the answer to your question, but I checked my photos. I have taken pictures of completely black-winged individuals on four other occasions--all at Lakeland Highlands Scrub. I see that mine is the only one posted in the images for A. georgicus. Should I post more? I have also photoed some with the clear area toward the trailing edge at the same place.

 
That's great. Thanks for your
That's great. Thanks for your help.

ID
Perhaps Anthrax aterrimus. It may be teneral. This might be giving the wing a different complexion.

 
Thanks Andy
How far can it safely be moved?

Moved for expert attention
Moved from ID Request.

Bombyliid of some variety. The experts will tell you more.

Bombyliid
Thanks. It looks just like one posted as Thyridanthrax atratus. Thanks for the quick response.

 
There's a resemblance...
...but T. atratus is restricted to the West Coast. I've been looking, and haven't found any that are as uniformly black as your specimen. I'll be interested in seeing what the experts have to say.
