Superfamily TENTHREDINOIDEA 31 



The taxonomy of this genus is based on female genitalia, though in many cases it is necessary 

 to have larvae and accompanying biological data for correct determination. Determination of a 

 single stage is sometimes not possible. Characters have not been found for separation of males. 

 A number of confusing species complexes remain to be studied, and the listing below is not so 

 clear-cut as it appears. Some complexes may represent a single species with a number of geo- 

 graphic or food plant races or may represent a number of separate species units. Complications 

 arise when apparently similar larvae produce different adults and different larvae produce 

 similar adults. Further taxonomic work on Neodiprion will have to involve studies of all stages 

 and biologies of each form from different parts of their ranges. Those who encounter 

 Neodiprioii in the field are urged to rear adults, keep associated larvae of each instar, and take 

 notes on their life cycles.
