Tep*hritis, right? Nope - Trupanea nigricornis

Tep*hritis, right? Nope - Trupanea nigricornis
Irvine Park, Orange, Orange County, California, USA
February 6, 2007
What do we need to get these to species? Hopefully, it's not a specimen in hand.(I'll do my part by purchasing a magic lens like the one used to shoot the other fruit fly.)

Another vote for trupanea
The posterior pair of scutellar bristles can sometimes be very small, and both genera lay eggs on flower heads, so teasing apart genera and then species can be tricky. Another area to look at is that Tephritis will usually have one preapical dorsal seta on the hind femur and will usually have more dark pigmentation in cell SC.

 
Nice addition.
Thanks :-)

Trupanea not Tephritis
Good job with the wings, the wing pattern is very important and helps a lot!. The other thing I wished to see was the scutellum, cause in Tephritis they have 2 pairs of setae, while Trupanea has only one pair... Otherwise the wings are very similar...
But thanks to the excellent wing wpictures, I'm rather confident to call this one Trupanea nigricornis.

 
Thanks for the ID and the move, Martin.
When I started taking pictures of fruit flies, I thought there were just two and that they differed solely by wing pattern. Well, I'm getting an education. I'll keep looking closely at and shooting these insects - and hope to have my hot new lens soon.
