These little flies have infiltrated my apartment from the outside garden. They are about 3-4mm in length and are gray with black spots. There are also other flies of similar size that have antenna with little hairs emanating from them (the antenna is the center stem part with the hairs growing outward), I'll try to get a picture of them. Does anyone know what these are (or the other flies)? Can they bite me?
