And Another Species of Knapweed Gall Fly
Fri 2010-07-16 
On the same stand of knapweed that I have, in the past month, seen Urophora jaceana and Urophora stylata, we now have Urophora quadrifasciata (Diptera: Tephritidae).
The number and variety of Tephritidae this year has been quite spectacular, at least compared with last year. But, unfortunately, the stand of knapweed in the Wilderness has now been mown, so it might be a while before I come across any more new species there.
