April or May, they are dark brown and hairy, and 

 then Hve in colonies in web-nests or tents. The eggs 

 are laid in bands encircling the young shoots, and are 

 found all through the winter. The caterpillars some- 

 times do much damage to the foliage, not only of the 

 apple, but also of the cherry, and occur also on haw- 

 thorn and other plants. 



Remedies. — Prune off and destroy any young wood 

 with eggs on it. The caterpillars remain in the webs 

 during wet or cloudy days, and on such days the 

 webs should be removed bodily and destroyed. 

 Spraying with arsenate or with weak emulsions 

 will destroy the caterpillars when they are out of 

 the webs ; a strong syringe should be used, instead 

 of, or as well as, the spraying machine, to destroy the 

 webs and any of the caterpillars which may be inside 

 them. Caustic winter washes will not destroy the eggs. 



Small Apple Ermine Moth {Hyponometita inali- 

 nelld). — Like that of the Lackey Moth, the caterpillars 

 of this moth live in colonies in web-nests. The eggs 

 are laid in roundish yellow or brown patches on the 

 twigs, protected by a covering of gum. They hatch 

 in October, the caterpillars then being very minute, 

 yellow with black heads. They winter under the 

 covering which protected the eggs, and emerge when 

 the leaves expand ; into these they burrow, living 

 concealed till the late spring or early summer, when 

 they eat their way out, and begin to feed on the 

 surface of the leaf. They then collect together and 

 build their web-nests. 



Remedies, — The same as in the case of the Lackey
