70 WOOD-NYMPH MOTHS. 
‘There are hardly two moths more unlike in general ap- 
pearance than the beautiful Wood-nymph and the Eight- 
spotted Forester, and yet 
their caterpillars bear 
such a close resemblance 
to each other that they 
are not readily distin- 
guished from each other, 
especially as they fre- 
quently feed side by side 
upon the same _ grape- 
vine. Generally how- 
ever, the caterpillar of 
grata appears a little 
later in the season. It is

one segment of same; e and f, eggs, greatly shown in Fig. 68, Plate 
enlarged; anp adult. After Riley. Sane 
The eggs are deposited upon the under side of the leaf, 
singly or in groups. The full grown caterpillars measure 
about an inch and a half in length; their bodies taper 
towards the head, becoming thicker near the posterior end. 
The head of the caterpillar is dull orange, with black dots; 
the body is pale bluish, crossed by orange and black lines 
which are arranged as shown in the illustration, Fig. 69. 
Each segment, with the exception of the head and the last 
one, is crossed by a brick or orange-colored band of uniform 
width, excepting the one on the twelfth segment, which is 
broader; on the last segment we find two such bands. All 
these bands contain black dots, from which a simple short 
brown hair arises. Each segment is crossed by six black 
lines; the breathing-pores are oval and black. Besides the 
erape-vine the caterpillars feed also upon the Virginia 
creeper, and occasionally upon the hop. They are most 
numerous late in summer, and do not web together leaves 
for shelter, but hide on their under side. When at rest, 
the caterpillar depresses the head and raises the anterior
