Hosts: This species is a common parasite of lepidopterous borers 

 in the stems of herbaceous plants. Material at hand includes rearings 

 from Epiblema strenuana (Walker) , E. otiosana (Clemens) and Mompha 

 eloisella (Clemens) in southern Ontario, and from a lepidopterous 

 borer and the weevil Mononychus vulpeculus (Fabricius) in Iris seeds, 

 in the vicinity of Ottawa, Ontario. 



This is one of the commonest species in the genus. It has a trans- 

 continental range in the Canadian and Transition zones. In the 

 west it extends northward in the Hudsonian zone and southward 

 in the Sonoran faunal area. Adults are on the wing from early spring 

 to late autumn.
