light and dark brown. 



The fore-wings of the moth (Fig. 67) ex- 

 pand about one inch, are much arched at 

 the middle of the front edge, and curve in 

 an opposite direction near the tip ; they are 

 of a light brown color, crossed by dark brown lines and bands. 

 The hind wings are yellowish, Avith the part next the body 

 blackish. Dr. Emmons (N. Y. Rep., 1854), states that this 

 insect passes the Winter in the egg state, and is to be found 

 in small clusters on the bark of trees infested the previous 

 year. 



In California there are several species found, which, if they 

 do not l)clong to the genus Joxotamia, are closely allied to it. 

 The young caterpillars appear early in the season, and .make 

 their nest under the Ijlossom leaf, or petal, of the apricot, 

 when the fruit is not larger than a garden pea, and feed upon 

 the skin or epidermis of the fruit on which they lodge. As 

 the fruit becomes larger and the insect gains in strength, it 

 bores int<j tJie fruit, destroying the pulp or mesocarp, and in 

 many instances eat part of the pit or stone. 



Remkdies. — When the tree is dormant Avash or spray thor- 

 oughly with No. o'6, to destroy any eggs deposited on the tree- 

 All infested leaves and fruit should be picked off and destroj'ed.
