upon it, besides the large sphinx caterpillars that devour 
its leaves, a small blue caterpillar 
(Fig. 211, and Plate VI. Fig. 7), 
transversely banded with deep orange 
across the middle of each ring, the 
bands being dotted with black, with the head and feet also 
orange, the top of the eleventh ring somewhat bulging, and 
the fore part of the body hunched up when the creature is 
at rest. These caterpillars begin to appear about the middle 
of July, and others are hatched afterwards, as late, perhaps, 
as the middle of August. When not eating, they generally 
rest upon the under sides of the leaves, and, though many 
may be found on one vine, they do not associate with each 
other. They live on the common creeper, as well as on the 
grape-vine. They eat all parts of the leaves, even to the 
midrib and stalks. When fully grown, and at rest, they 
measure an inch and a quarter, but stretch out, in creeping, 
to the length of an inch and a half, or more. Towards the 
end of August they begin to disappear, and no more will be 
found on the vines after September. They creep down the 
vines in the night, and go into the ground, burying them¬ 
selves three or four inches deep, and turn to chrysalids with¬ 
out • making cocoons. The chrysalis is dark brown, and 
rough with elevated points. The moths begin to come out 
of the ground as soon as the 25th of June, and others con¬ 
tinue to appear till the 20th of July. Though of small 
size, they are very beautiful, and far surpass all others of 
the family in delicacy of coloring and design. The name 
of this moth is Eadryas grata^ (Plate VI. Fig. 8), the first 
word signifying beautiful wood-nymph, and the second agree¬ 
able or pleasing. The antennse are rather long, almost 
thread-like, tapering to the end, and not feathered in either 
sex. The fore wings are pure white, with a broad stripe 
along the front edge, extending from the shoulder a little 
beyond the middle of the edge, and a broad band around the 
Fig. 211. 
* This insect is the Bombyx grata of Fabricius.
