FRUIT INSECTS 



length, in thin cocoons placed in crevices of the bark, under 

 trash, or just beneath the surface of the ground. The emer- 

 gence of the moths extends over a considerable period, from 

 early June until the middle of August in New York. The webs 

 begin to become conspicuous in July and are most abundant 



in August (Fig. 117). 

 In the District of 

 Columbia the first 

 brood of moths ap- 

 pears soon after the 

 leaves are fully de- 

 veloped ; that is, 

 about June first, the 

 second brood occur- 

 ring in July and 

 August. 



The moths expand 

 about IJ inches and 

 vary in color from 

 satiny white to whitc^ 

 heavily spotted with 

 })lack or brownish 

 spots. Some of these 

 forms have received 

 specific names, but 

 it is now generally 

 l)elieved that we have only one species which is highly vari- 

 able. More recently Dr. H. H. Lyman has attempted to 

 separate two forms on the color of the larvae, but the evidence 

 presented is hardly convincing. More extensive rearings are 

 greatly needed. 



The moth lays her pale green eggs in clusters on the upper 

 or under surface of the leaves, and covers the cluster with white 

 hairs from her body (Fig. 118). The cluster is about f inch
