I'm not sure of the ID of this small beetle. I saw it while observing the bees visiting the flower of Armeniaca vulgaris. I was surprised to see it hunting aphid.
I saw these flies chasing each other on the trunks and branches of Juglans mandshurica bathed in the sunshine. It seems that they were mating in an unusual way, with the male's front legs touching the female's tail. At first I thought they were robber flies. But after checking the wing vein, I thought they must be something else, most probably something new for me.
My friend described this new species of fungus gnat and named it by my colleague from University of Ostrava - Dr. Sevcik. These are the pupae of the type specimens.
