Family D EU TEROP HL E BUD AE 



This family contains a single genus with five de- 

 scribed species, two of which occur in the western 

 United States. The North American species were 

 described by Pennak (1945) and Wirth (1951), and 

 Pennak (1951) summarizes what is known about the 

 family. Since the species generally occur at high 

 altitudes, the name "mountain midges" has been 

 given to the family. The adults are rarely collected. 

 Deuterophlebia shasta Wirth (fig. 14:13) has been 

 found only in Shasta County, California, and D. color- 

 adensis Pennak (fig. 14:12) is possibly confined to 

 the Rocky Mountain region. 



The larvae and pupae are found in cold mountain 

 streams on the upper surface of smooth rocks, either 



in the riffle or splash area or where the water flow is 

 verv shallow and swift.
