THE TXJNG FLIES 



(Families Scatophagidce and Heteroneuridce.) 



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 some- 

 times yellowish ' 

 or with a broad 

 yellowish stripe on 

 a dark background. 

 The flies of this 

 family are popularly 

 known as dung 

 flies and are at- 

 tracted to and breed 

 in dung of various 

 animals, and also 



in decaying VCge- Fig. 99. Scatophaga furcata. (Author's Illustration.) 



table matter. 



The Heteroneuridae are rather small, slender, yellowish or 

 black species, which are found in foul, damp places, and whose 

 larvae are found under the bark of trees and in similar situations.
