Last Tuesday I collected two Tephritis specimen by sweeping the vegetation in Terneuzen, the Netherlands. As I am not 100% sure about my ID, I would like to ask your opinion about it. The other Tephritis I will post in a separate thread. I made 4 pictures from nearly the same angle, because they look very similar but I think they are two species.

This one I think is Tephritis crepidis, because there are two pairs of light spots around the R-M crossvein. Am I right?

The wing

The abdomen

And the notopleural bristles

They are both Tephritis matricariae. A second pair of (weak) hyaline spots around r-m is not unusual in T. matricariae.
Wingpattern in Tephritis crepidis is more chaotic and the hyaline spot in the top of the wing rarely is closed in by the apical fork.

Thanks Ben, that makes sense. I didn’t know a second pair of weak spots could be present in T. matricariae.

I agree with Ben. T. matricariae.
