 The species occurs in deciduous woods and is often very common. 

 It is usually on low shrubs or herbage, or on the forest floor. 



Considering its abundance as an adult, rearing records are scanty. 

 Those on the pin labels of specimens before us are: 9, from Halisidota 

 caryae, May 25, 1908. 9, from Halisidota sp., Ithaca, N. Y., Apr. 

 26, 1925, P. P. Babiy. 9, from pupa of Halisidota'!, Pittsburgh, 

 Pa. 



This species is in the Alleghanian and Carolinian faunas. Its 

 habitat is the undergrowth of deciduous woods, where it is often very 

 common. Adults occur from spring to early fall. It has been reared 

 from Halisidota.
