ocddentalis G. and R., Acronycta 



The larva of Acronycta ocddentalis is hairy, with a dark head and dorsal 

 stripes. The remainder of the body is at first whitish but in later stages 

 is reddish. Larvae of this species were feeding on Crataegus punctata 

 foliage from August 13 to September. The species is not common. 



pyramidoides Guen., Amphipyra 



The larva of Amphipyra pyramidoides is green, with a white dorsal 

 and two yellow lateral stripes, and is found feeding on native hawthorn 

 leaves in May. One larva constructed a silken cocoon among dead leaves 

 on the ground on June 2 and the moth emerged on July 18. The species is 

 not common. 



raddijffei Harv., Acronycta 



The larva of Acronycta radcliffei is greenish or black, has a dorsal line 

 of green or brown with faint yellow and red lines, has a hump on segment 

 12, and is sparsely hairy. It feeds on the leaves of Crataegus punctata 

 from June 29 to July 22. The species is not common. 



super ans Guen., Acronycta 



The larva of Acronycta superans is green, with a black dorsal line 

 widened into a spot on several abdominal segments and with the last 

 segment angularly elevated. There are few hairs on the body. It was 

 feeding on Crataegus punctata leaves from June 9 to July 1, and pupated 

 in a silken cocoon among leaves and decayed wood on the ground. The 

 moth emerged on July 23. Only one larva was found. 



Notodontidae 



concinna A. and S., Schizura (Red-humped apple caterpillar) 



The brownish, red-humped larvae of Schizura concinna feed on leaves 

 of native hawthorns during July, August, and early September. Occa- 

 sionally they defoliate several branches of a tree, but they are not generally 

 injurious as is Datana ministra. They seem to prefer apple to hawthorn. 

 On July 27, 1918, a count was made of the infested trees in several thickets 

 where seedling apples and hawthorns were growing together. Although 

 the hawthorns were much more numerous than the apples, the latter 

 had forty-six infested trees while the former had only three. 



manteo Doub., Heterocampa 



The larva of Heterocampa manteo is bright green marked with red. It 

 was found feeding on the foliage of native hawthorns in late June and in 

 July. The species is not very common. One larva taken from a Crataegus 

 punctata tree on August 15 continued to feed in the cage until September 

 2, when it wandered away to find a suitable place for spinning its cocoon.
