Autumn house-flies look a lot like house-flies but can be distinguished by the clearly striped yellow with grey abdomen and the eyes of the males that almost touch each other on top of their heads.
Female autumn house-flies lay their eggs on manure in meadows. The larvae develop in the manure and pupate in the surrounding soil. The adult flies feed on body secretions of the cattle and sometimes drink blood, although they can’t bite through the skin of people or animals. The overwintering behaviour of the autumn house-fly is almost the same as that of the cluster fly and both species can jointly use the same building.
