Ulomorpha Osten Sacken

Ulomoiyha is unquestionably closely allied to Pilaria despite the 

 distinctive appearance given by the conspicuously hairy wings and the 

 sessile or subsessile cell ^3. The adult flies are usually found by being 

 swept from rich herbaceous vegetation in low, shaded areas. The 

 innnature stages live in rich organic earth in woods.
