## Summary

The lesser house fly (Fannia canicularis), commonly known as little house fly, is a species of fly. It is somewhat smaller (3.5–6 mm (0.14–0.24 in)) than the common housefly and is best known for its habit of entering buildings and flying in jagged patterns in the middle of a room. It is slender, and the median vein in the wing is straight. Larvae feed on all manner of decaying organic matter, including carrion. Though similar in appearance and habits, it is no closer in relation to a house fly than any other fly in order Diptera is.
