ICHNEUMON-FLIES, PART 2: EPHIALTINAE 295 



This species is widespread but not very common from the Rocky 

 Mountains, westward. It occurs also in Eurasia. The zonal range is 

 from the Hudsonian to the Upper Austral. Adults occur throughout 

 the growing season. The hosts are a wide variety of Lepidoptera with 

 exposed or poorly protected pupae.
