Larva. — When mature, over one inch long; bright yellow; head, and 

 two small protuberances on the back carrot-red ; back ornamented with 

 four cream-colored brush-like tufts ; two long black plumes near the 

 head and one near the posterior end of the body; sides clothed with yel- 

 low hairs ; brown or black stripe on the back, and a dusky stripe on each 

 side. 



Cocoon. — Gray; spun on the inside of a leaf. Texture loose and the 

 silk interwoven with numerous hairs from the caterpillar. Chrysalis, 

 enclosed in the cocoon, oval, brown or sometimes whitish below, covered 

 with whitish hairs or down. 



Perfect Insect (female). — Wingless or wings mere rudiments; light 

 gray, oblong-oval ; body distended with eggs ; legs long. 



Perfect Insect (male). — Winged, expands an inch and a quarter; fore 

 wings crossed by wavy bands of darker shade ; a small black spot on the 

 outer edge of the wing toward the tip ; beyond it an oblique blackish 

 stripe, near the outer hind angle a minute white crescent ; body gray,

Life History. 

 During the winter months there will occasionally be found in 

 the orchard, dead leaves attached to the branches of the trees. 

 Upon examination these will usually be found to contain an 

 empty, gray cocoon with a mass of eggs attached to it, as 

 described above. These eggs hatch, in Maine, about the first of 

 June, or earlier farther south. The young larvae at once begin 

 to devour the leaves of the tree. When disturbed they lower 

 themselves by means of a silken thread which they climb when 

 danger is past. The beautiful caterpillars described above feed 

 about two months and then spin their cocoons. The moths soon 

 emerge and the wingless females, being little more than ani- 

 mated masses of eggs are sluggish. The males, having wings, 

 are able to fly, and they meet the females while resting upon the 

 empty cocoon to which the mass of eggs is finally attached. If 

 there is only one brood, the eggs do not hatch until the following 

 spring ; if two broods, the eggs soon hatch, producing the second 

 brood of caterpillars which complete their growth late in the 

 season and enter the chrysalis state. The moths soon emerge, 

 mate, and the female lays the eggs on the cocoon, completing the 

 life history. 



Remedies.
