The small moth has only about one-fourth inch expanse of 

 wings. Fore wings whitish, tinged with pale yellow and dusky 

 brown, (fig. 14). 



This insect spends the winter in the pupa state in the cocoon, 

 usually attached to the twigs and branches of the host plant. 

 About the time the leaves unfold, the moths come forth and lay 

 their eggs upon the tender, foliage. The larvae are full grown 

 in July. 



In September or October the cocoons in which the pupae 

 spend the winter are formed. The larvae feed externally upon 

 the foliage, the upper epidermis and pulp eaten away in patches, 

 the veins and lower epidermis intact. 



REMEDIES. 



Jar the trees when the larvae are full grown and they will 

 suspend themselves by threads and can be swept down by a 

 broom and killed by hot water or crushed. 



Apply sprays of kerosene emulsion or lime-sulphur wash in 

 winter, to the branches that bear the cocoons. 



Spray with arsenical poisons as for other leaf-eating insects 

 in summer when the caterpillars are feeding. 



Tussock Moths. 



I. white-marked tussock (Hemerocampa I euco stigma) . 



II. antique tussock {Notolophns antiqua). 



The conspicuous white egg masses of these moths are depos- 

 ited late in the summer or in the fall upon the cocoons from 

 which the female moths emerge. As the hairy cocoons are 

 commonly attached to the rough bark, or twigs of trees the 

 caterpillars infest, the egg-masses are readily found at any time 

 after the leaves have fallen. The eggs which the white-marked 

 tussock deposits are covered with a white frothy substance 

 which becomes brittle upon exposure to the air. The antique 

 tussock does not protect its eggs in this manner but leaves them 

 uncovered upon the cocoon (fig. 39). 



The caterpillars which emerge from these eggs in the spring 

 are most grotesque in appearance. The caterpillar of the white- 

 marked tussock moth when full grown has a shiny coral red
