These are commonly called dung-flies. Some of the species 

 resemble Anthomyidae, but the squamae are quite small and 

 there are more than four abdominal segments visible. Most 

 of them are brownish or yellowish in color and are common 

 in pastures about cow-dung. In some of the species the habits 

 are predatory. 



The larvae have been bred from excrement and from the 

 stems of plants. Aldrich lists 1 1 8 species from North Amer- 

 ica in his Catalogue.
