We find the subspecies in moist deciduous woods, usually on foliage 

 near the forest floor, or females sometimes on the dead leaves of the 

 floor. Females appear with the fh'st warm days of early spring and 

 are among the more conspicuous of the early spring ichneumonids. 

 Males appear about six weeks later and both sexes are common thi-ough 

 the summer and into the fall. It is almost certain that overwintering 

 is as adult females, probably under dead leaves. 



This subspecies occurs in the Alleghanian fauna and in parts of 

 Colorado, Wyoming, and British Columbia.
