Guess who I am!
Gymnosoma sp. (Diptera, Tachinidae) couple. Body size: 6 mm.
Yet another common Tachinid species for a good early morning fun. I found them in this situation and thought they are still enough and motionless. After finishing the sequence realized the significant movement of the female's antennae. Luckily, I could resolve it in the stacking program, using 2-3 frames from the whole stack. Find some details in the comment below!
