Near Jubilee Pass, Death Valley National Park, Inyo County, California, USA
February 18, 2007
Going through some old photos, I noticed a number of shots of a tephritid taken within about 5 minutes of each other. I snapped them as the tiny guy flew from spot to spot on an interesting desert plant, Sticky Ringstem (Anulocaulis annulatus). Not until preparing to post them here did I realize there were actually two different flies...both species of Trupanea I think. The other fly is shown here. (Besides having different wing patterns, the two flies also have different eye-color...green here...though I don't know if that's significant, may change with lighting.)

I'm guessing this is Trupanea pseudovicina as a result of careful comparison with the wing pattern plates on pages 108-117 of "The Fruit Flies or Tephritidae of California", published in 1963 by Foote & Blanc (downloadable as a PDF here). I know that's not a conclusive method...hoping for feedback from other more experienced Dipterists out there (Martin, Ron,...?)

Moved from Tephritini.

Trupanea pseudovicina wing pattern matches, agreed.
Anyone who thinks these comparisons are easy is encouraged to check the Foote & Blanc PDF! While no expert and having no personal experience with this species, I agree with Aaron's ID.

Hopefully, Martin will comment also.

 
this is a difficult one... ev
this is a difficult one... even with the help of Foote et al 1993, I am not completely sure if it is signata or pseudovicina..... it is a male and the characters are right in between and hard to see from the picture...

 
Thanks Ron
I appreciate your interest and feedback! :-)
