golden Long-legged Fly - Amblypsilopus bicolor - female

golden Long-legged Fly - Amblypsilopus bicolor - Female
Baiting Hollow, Suffolk County, New York, USA
July 12, 2008
I thought that this is a long-legged fly but I have looked though Dolichopodidae (Longlegged Flies) in the guide and don't see a match.

I am wondering about the gray on the side of the thorax. I haven't seen that in such a pronounced way before and am wondering if it is anatomical or disease.

Moved from Amblypsilopus. A. unifasciatus has less yellow, and fewer complete bands (presumably the origin of its name).

Thanks, John!!!

Moved from Condylostylus.

Probably Amblypsilopus unifasciatus (Say).

The gray seems to be common in this subfamily.

I think this is what we call "probably Pelastoneurus"
Several are filed under Dolichopodinae, including:
But - caution! - I'm no expert.

Looking through Taxonomy for "Pelastoneurus" reminds me of when we used to send new Interns to Central Supply to get a Fallopian Tube. None to be found there! Still makes me laugh.

Back to fly business.
These looked close but I couldn't reconcile the wings.

Thanks for always being here to help.
I really need and appreciate the help.


My pleasure. Glad to help whenever I can.
LOL! In junior high, a shop teacher had us looking for elbow grease. So a couple years later, we balked when a physics teacher tried to send us in pursuit of vacuum wax! The fun never ceases...

Good laugh in the middle of the night.
Thanks Ron.

I enjoyed seeing this again, Lynn.
Thanks to John for reawakening the post with his comment.

Or Condylostylus?
That depressed area between the eyes points towards Condylostylus or maybe one of its relatives.

Probably Amblypsilopus
This is probably Amblypsilopus (i.e. "one of its relatives"); females are harder to identify.

Condylostylus is looking pretty good including the wings, as far as I can tell anyway.

Still can't find an exact match, but these flies have not yet been sorted out very much.

Thanks very much, Lynn
