Autumn House Fly Musca autumnalis

The Autumn Housefly can be a real nuisance. In autumn it may invade our homes in great numbers, looking for a place to hibernate. In summer it pesters horses and especially cows by sitting on and near the eyes. That is why it is also known as the Face Fly. The Autumn House Fly may transfer a desease as well as a parasite. In spite of both the common name and the scientific name it not only appears in autumn, but from summer onwards. The larvae live in dung. Adults feed on animal juices (tears, blood) and nectar from flowers. Most of the flies found on cattle are females, for they need more proteins to produce the eggs.
