88 INSECTS INJURIOUS TO THE APPLE. 



When ready to transform, it attaches itself to a limb and 

 there encloses itself in a gray cocoon, which appears like a 

 slight swelling of the limb, and in this enclosure it changes 

 to a brown chrysalis, in which state it remains until the 

 month of June following, when the perfect insect escapes. 



The moth (Fig. 86) is of a tawny reddish-brown color, 

 with the hinder and inner edges of the fore wings and the 



outer edges of the hind wings 

 notched ; the notches are mar- 

 gined with white. Both pairs of 

 wings are crossed by a rather 

 broad, interrupted, whitish band, 

 not very clearly shown in the 

 figure, which, on the anterior 

 wings, does not always extend to 

 the front margin. In the female the pale bands and dark 

 lines are sometimes wanting, the wings being almost entirely 

 of a red-brown color. The moth measures, when its wings 

 are expanded, from an inch and a half to an inch and three- 

 quarters across. 



The eggs are laid on the leaves of the apple-tree late in 

 June, and are very pretty objects under a magnifying-glass. 

 They measure about one-twentieth of an inch long, are oval, 

 flattened at the base and also above, and a little thicker at one 

 end than at the other. In color they are white, with peculiar 

 black markings ; at each end is a crescent-shaped stripe, with 

 a dot below it, and on both the flattened surfaces there are 

 markings like eyes, each formed by an oval spot in the 

 centre, with a curved stripe above and a shorter straight one 

 below; between and parallel to the two eyebrow-like marks 

 there is another black stripe. The whole surface is covered 

 with a net-work, the meshes of which are irregular, with a 

 depressed dot in the centre of each. This insect feeds also 

 on the cherry and the oak. It is not at all common, and 

 probably will never be a source of much annoyance to the 

 fruit-ffrower.
