THE PYRAMIDAL GRAPEVINE CATERPILLAR. _Pyrophila pyramidoides_ (Guen.) This caterpillar, Fig. 21, is generally found on grapevines early in June, but also feeds on apple, plum, raspberry, maple, poplar, etc. It is about an inch and a half in length, with the body tapering toward the head; of a whitish green color, darker on the sides; with a longitudinal white stripe on the back, broader on the last segments. Low down on each side is a bright yellow stripe, between this and the one on the back is another less distinct, and the under surface of the body is pale green. [Illustration: FIG. 21.] The caterpillar is fully grown about the middle or last of June, when it descends to the ground, draws together some of the fallen leaves, and makes a cocoon, in which it soon changes to a mahogany brown pupa. [Illustration: FIG. 22.] In the latter part of July the perfect moth, Fig. 22, emerges, measuring, when its wings are expanded, about one and three-fourths inches; the fore wings are dark brown shaded with lighter, with dots and wavy lines of dull white. The hind wings are reddish, or of a bright copper color, shading to brown on the outer angle of the front edge of the wing, and paler toward the hinder and inner angle. |
