Dung Flies

(Families Scatophagidae and Heteroneuridae.)
We are coming now to a long series of small families of rather small flies which are not especially interesting or especially remarkable.

The Scatophagidae are rather slender, medium sized flies, generally smooth, but rarely with some bristles and yellowish hairs. In color they are usually black and shining, but sometimes yellowish or with a broad yellowish stripe on a dark background. The flies of this family are popularly known as dung flies and are attracted to and breed in dung of various animals, and also in decaying vegetable matter.

The Heteroneuridae are rather small, slender, yellowish or black species, which are found in foul, damp places, and whose larva are found under the bark of trees and in similar situations.
