webs, but beyond this, they have nothing in common. Their habits 

 are different, their markings and life history all are different, yet 

 some who have noted this dissimilarity still cling to the opinion 

 (or are inclined to) that it is the second brood of the tent cater- 

 pillar, and that the variations result from natural causes; but there 

 is no ground for this supposition. They are of entirely different 

 species. 



The moth usually appears in June and July; some earlier and 

 others later. The wings are pure white, and when spread, expand 

 an inch and a quarter or over. The legs and lower portion of the 

 body have a yellow shade. The eggs are laid in clusters on the 

 leaves; generally near the extremity of the branches. These eggs 

 hatch out from time to time, during June, July and August, and the

young worms commence at once to enclose the leaf with a web, 

 each one joining in the work. It is this peculiarity that gave rise 

 to its generic name, Hyphantria textor, "the weaver." Under the 

 shelter of this web they feed on the pulpy portion of the leaf. As 

 the leaves enclosed in this shelter are consumed, they extend their 

 web from time to time, and often enclose the entire limb on which 

 they are located. Here they may be found, at all times before they 

 arrive at maturity. They seem to thrive on most every kind of 

 tree and shrub. Their unsightly webs may be seen on the tall forest 

 trees and the oak grub. The apple, the elm, and the cherry trees, 

 however, seem to be their favorite habitat; on them their webs are 

 more numerous and attain a larger size. 



"When young the larvas are of a light yellow color; head black, 

 and a few brownish hairs scattered over their body. When mature,
