Subfamily ALLANTINAE 



Members of this subfamily are associated with various plants. Some hosts are strawberries, 

 raspberries, roses, violets, and dogwood. After feeding is completed, larvae of many species bore 

 into fruits, wood, or other suitable substances for pupating or overwintering. The occurrence of 

 larvae in these secondary hosts is sometimes more significant if in cultivated fruits or structural 

 wood, but it is purely incidental depending on their proximity to the true host plant. Adults of 

 this subfamily are medium to large sawflies and may be either rather stout or elongated.
