This species is the oak twig girdler. The egg is deposited on the side of 

 the twig near the terminal bud, and the resulting larva encircles the twig beneath 

 the bark, causing the death of the part beyond the burrows. The adults 'feed 

 on the foliage, eating out irregular patches near the edges of the leaves. 



Reared from girdled branches of beech (Fagus americana) and hickory 

 {Hicoria ovata) (Knull). 

 A. arcuatus var. coryli Horn.
