Notes on the Life History of Chrysophanus Gorgon. 



BY J. G. GRTJNDEL, Alma, Santa Clara Co., Cal. 



The female Chrysophanus gorgon deposits eggs in the forks 

 of a long-stemmed species of Eriogonum, a plant which only 

 grows on the very dry hillsides. 



Only one egg is laid in a given fork, but others repeat the 

 act until as many as five or six are found in one place. 



The eggs are deposited in June, and the young larvae emerge 

 in or about the latter part of August, and make their way to 

 the lower part of the plant and hide among the old leaves feed- 

 ing but very little and only on the upper or green side of the 

 leaf, which the larva resembles in color, being of a dark green. 



The larvse feed only during the night and early morning up 

 to about 9 o'clock, A. M., growing but very slowly, being only 

 one-eighth of an inch long by the latter part of October. 



After several moultings the appearance of the larvae changes 

 to a furry light green, nearly white and exactly resembling the 

 under side of the leaves upon which only it feeds and on which 

 it also fastens its cocoons, becoming full fed about May ist, a 

 year from the time the eggs were laid, and when full grown 

 one-half inch long, with body thick at middle and tapering to 

 both ends ; head very small and hardly to be seen, even when 

 feeding, and appears to be lifeless when removed from the plant 

 and remains so for several hours.
