Way of life

Acerocnema macrocera in copula

Acerocnema macrocera is an early spring species whose phase of activity begins in the first third of March and ends in early May. Adult flies can be found in stocks of the fingered larkspur ( Corydalis solida ), where partner search and mating also take place. The females lay their eggs on the developing pods of the lark spur.
