Agree with Ted…

Wing pattern and other features match. This is a male.

See reference here.

Another common name...

I found this common name used on several websites: UV Knapweed Seed Head Fly. The "UV" refers to the U and V patterns on the wings.

Resembles

Urophora quadrifasciata but I am not 100% sure; please wait for an expert.

Yes

Thanks Ted, I searched through the fruit fly images and somehow missed this one. The wing pattern looks similar.
