Tephritidae--Trupanea bisetosa? - Trupanea nigricornis - Female
Anza-Borrego Desert State Park, San Diego County, California, USA
March 7, 2007
Size: BL~3.5, to wing tip 4.5
Another guess! I went with T. bisetosa rather than T. nigricornis because the antennae appear yellow. We saw this on Brittlebush in Borrego Palm Canyon. Quite a beautiful pattern on the elongate wings!

I did some more reading and the males of nigricornis have black antennae the males of bisetosa have yellow antannae, but the females of both species have yellow antennae... and yours is a female... and it is nigricornis...

The important character is if
The important character is if the Y structure at the end of the wing has a stem (of the Y) which is as thick as the proximal arm of the Y (nigricornis) or if it is twice as thick as the proximal stem (bisetosa). Therefore I would vote for nigricornis, but it is difficult to see from this picture.
