CHAPTER XXXVI. 



The Fall Web Worm. (Cal.) 



(Hyphantria textor. — Harris. ) 



Order, Lepidoptera ; Family, Bombycid^. 



[Living under a Aveb on apple, hickory, walnut and other 

 trees, and feeding upon the upper surface of the leaves ; six- 

 teen legged caterpillars of a yellow and black color, their bodies 

 sparsely covered with whitish or brownish hairs.] 



" This insect passes the Winter in the pupa state, and the 

 moth emerges during the month of May. The female deposits 

 her eggs in a cluster on a leaf, generally near the outer end of 

 a branch. Each worm or caterpillar (Fig. 57a} begins spin- 

 ning the moment it is hatched, and by their united efforts 

 they soon cover the leaf with a web, under which they 

 feed in companies, devouring only the pulpy portion of the 



leaf. As they increase 

 ^^' ■ in size they extend their 



web, but alway remain 

 and feed underneath it.''
