 Those outside of this range are: April 26 in Delaware County, Ohio; 

 May 19 at Great Falls, Va., May 21 at Urbana, 111.; May 28 at Syra- 

 cuse, N. Y.; September 14 in Montcalm County, Mich.; and Septem- 

 ber 15 in Midland County, Mich. This is the only species of the 

 subfamily with rearing records for North America, and these are 

 meager. Two records indicate it as reared from hosts in Carya glabra 

 and in climbing bittersweet, and F. DeGant reared it at Cleveland, 

 Ohio, from a pemphredonid in a rose stem. The type of Foenus area 

 was reared from a cocoon found under bark. 



This subspecies occurs from the Atlantic to the one-hundredth 

 meridian, mostly in the Transition Zone. In the colder part of its 

 range it intergrades freely with the subspecies 0. assectator assectator.
