Family TIPULID^E 



Fig. 1. Nephrotoma erythrophrys Will. Wing and head from side. 



The craneflies are usually quite easily distinguished from 

 the other diptera by the long legs and characteristic wing 

 venation. They have a blunt snout and often very long palpi. 

 One of the other distinguishing marks of the family is a 

 V-shaped suture on the upper part of the thorax. A few 

 species are wingless. The adults frequent meadows and edges 

 of woods where there is a rank growth of vegetation and 

 most are found near water. Many species come to lights. 



The larvae are aquatic or semi-aquatic and are usually 

 root feeders and scavengers. The terrestrial larvae are com- 

 monly known as "leather jackets" and may injure root crops.
