Hi,
against my usual habit I am requesting two species at the same time. Found them in a park in Vienna in mid April and only later realized they apparently belong to different species. Length about 6mm
Is the upper one Actina chalybea and the lower one a Beris species?

All requests are from the urban area of Vienna, if not otherwise stated.

My Diptera observations (and other living forms) can be found here, and corrections or comments over there would also be appreciated.

Both are Actina chalybea. Sexual dimorphism...
