284 INSECTS AFFECTING SHADE TREES 



The Lime-tree Winter Moth. The female moth of this species 

 (Erannis tiliaria Harr.) is wingless, spider-like in appearance, 

 with a yellowish-white body. The male has large, delicate wings 

 of a buff color. 



Life History. Pupation occurs in the ground, the adults emerg- 

 ing in the fall, at which time the females climb the trees, depositing 

 their oval, pale-yellow eggs in clusters on the branches. These 

 eggs hatch in the spring and the caterpillars feed during the summer. 



Flo. 287. The lime-tree winter-moth; larvae, adult male above, adult female below. 



(U. S. Bu. Ent.) 



The caterpillars are measuring worms, similar to true canker 

 worms, but larger and differently marked. The head is dull yel- 

 low. The body is yellow above, with many longitudinal black 

 lines. The full-grown caterpillar is about one and one-fourth 

 inches long. They feed on the foliage of the elm, basswood, 

 hickory, and many other trees (Fig. 287). 



Control. Arsenical sprays are practical on small or medium- 

 sized trees and necessary on large trees in extreme cases. Banding
