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.
