SUPERFAMILY NEPTICULOIDEA 91 



Canada and the northeastern United States. In October, the 

 tiny green caterpillars are sometimes seen hanging by silken 

 threads from the leaves. They soon find their way to the twigs, 

 where they spin small, oval, dense, brown cocoons about J inch 

 long on the bark, often in a crotch. These cocoons resemble, and 

 could be easily mistaken for, Lecanium scales. In May the 

 caterpillars transform through brilliant green pupae to the minute, 

 shining, purplish-black moths with tufted, reddish-yellow head, 

 that emerge early in June. Thus far no very serious injury has 

 has been recorded.
