Hello friends
To my mind this appears to be
Phytomyza bipunctata. Can it be confirmed? The fly keys out well enough when I use Spencer (1976) and his drawing of the aedeagus is not very different from what I see in the microscope. But you never know …
Denmark, Amager. Malaise trap mid-May 2018. Willow, birch, herbs and grasses on reclaimed land. No Echinops spp. as far as I'm aware. Several kilometres to the nearest gardens.
Help will be much appreciated :)
