Family LONCHOPTERIDiE 



Fig. 26. Lonchoptera lutea Panzer. 



Very small flies with pointed wings, commonly known as 

 "spear-winged flies." When at rest the wings are folded 

 flat, one over the other, on the abdomen. The venation 

 alone will distinguish them from all other families and sug- 

 gests that of the Psychodidae. They are found in grass 

 along streams and the individuals are quite common. There 

 is only one genus in the family and very few species, three 

 occurring in North America. Little is known of their habits. 

 The larva? are found on the ground under vegetable material.
