The winter is passed in the eggs state, the larvae developing in early 

 spring pools, particularly in spruce swamps. None were found in the 

 flood-pools referred to as breeding places for diantaeus and others. The 

 adults are severe biters, and can be found till frost in the northern woods, 

 although there is but a single annual generation. 



Distribution: Canadian forests from Atlantic to Pacific except the 

 rainy Pacific belt; mountains of New England, New York and Minnesota.
