These figures show that a little over 40 per ct. of the 2,500 
cocoons failed to produce moths. Also that less than 47 per ct. 
of those that hatched were females and that the greatest number 
of moths escaped during the first five days of July. <A little over 
123 per ct. were parasitized and more than 28 per ct. produced 
neither moths nor parasites. 
The moths are active, restless insects. They fly only at dusk 
and during the night. The females are ready to lay eggs soon 
19 Cocoons to the number of 3,757 were sent in from various sections of the 
State. Nearly 1,000 of them had hatched before being gathered, leaving about 
2,700 unhatched. For most of these cocoons the writer is indebted to Mr. A. 
Rk. Eastman, Waterville N. Y., Mr. D. H. Burrell, Jr., Little Falls, N. Your 
J. B. Tuckerman, Cassville, N. Y., and Mr. J. M. Budlong, West Schuyler,
