Kim, I wouldn't have a clue but Peter Cranston suggested that of the 3 midges: (a) a female non-biting midge (family Chironomidae) (b) a female biting midge (Ceratopogonidae) (c) a second female biting midge (Ceratopogonidae) b and c will feed on you given the chance, a is likely the female of the male that was inside your door and another at the might outside. Imatures are bloodworm found in water containers and gutters - same places as mossies. Pete
