Adults occur from rather early in the spring to late in the fall. 

 After the first frosts of the fall they are still easy to find on warm 

 days, and because other ichneumonids are scarcer then, this species 

 seems to be relatively common. The hundreds of collection dates 

 available indicate that it has no real peaks of abundance except as 

 influenced by local conditions, and can be collected any time during 

 the growing season. The characteristic habitat is the shrubby growth 

 of rather open woods or overgrown fields. 



The species has been reared more than any other Nearctic ichneu- 

 monid. Rearing records on the pin labels of the specimens studied 

 are as follows: 1 rearing or reared lot from Acleris hastiana, 2 from A. 

 minuta, 1 from Acleris sp. on Carpinus, 2 from Acrobasis betulella,
