INSECTS INFESTING THE APPLE TREE.

smooth bark. In one case, where four hundred apple trees 

 were dug up, the larvae were found in large numbers in the 

 roots of such trees as were decayed at or above the surface of 

 the ground. 



Fig. 79. — a, nest of lar- 

 va as it appears on inside 

 of bark when taken otf 

 tree — color, drab ; />, pupa 

 or chrysalis — color, dark 

 amber ; c, appearance of 

 larva when cover is re- 

 moved from Winter nests 

 — color, body yellowish- 

 white, head dark brown ; '^i 

 d, appearance of bottom -^ 

 of Winter nest on bark 



when larva is removed in the following Spring ; c, a position 

 the larva takes when looking for a tree or place to make its 

 nest when ready to assume the pupa or chrysalis form. [Note : 

 when the larva? are full grown and ready to assume the pupa 

 or chrysalis form, the color is light pink]. /, the moth, at rest 

 carries its wings like a steep roof; g, moth with wings spread, 

 length of body five lines, spread of wings nearly nine 

 lines — color, body and legs rich bronzed light drab, 

 fore-wings mottled with gray and drab, with dark copper 

 bar across hind margin on which is a golden oc^^ellated 

 patch near inner angle, hind-wings plain drab a little darker 

 than body (the moth after depositing eggs has assumed a light 

 drab color on fore-wings, and copper bar changes to a very 

 light color, scarcely perceptible, caused probably from flying 

 among the branches and leaves) ; h, head of larva as seen 

 through a glass magnifying nine times ; i, in this figure it was 

 intended to represent the pupa or chrysalis case protruding 

 through nest prior to moth leaving it, but represented 

 as larva to show better. [Note : the figure would be correct 

 if the chrysalis (6) was represented instead of larva (c) ; the 

 figures a, b, c, d, e, and /, are natural size ; y is a. little larger 

 than natural size; h, as described]. See, also, Fig. 80.
