single hole is made in each berry just large enough to admit 
the body of the worm. Like all caterpillars of such insects 
these worms are very active, and if their house is ever so 
little disturbed they leave it very suddenly and drop to the 
ground by a silken thread, which enables them later to re- 
ascend to their dwelling places. When full grown thiscater- 
pillar, which is shown in Fig. 204% suspended by a thread 
and also upon a berry, is about three-quarters of an inch 
long; its body is thickest in the middle, tapering slightly 
toward each extremity, of a pale green color, sometimes 
with a yellowish or reddish tint, glossy and semi-trans- 
parent. It has a small, horny and pale brown head, the 
cervical-shield has also the same color. Before the berry 
ripens the larva drops to the ground where it makes a snug, 
brown and paper-like cocoon among the dead leaves and 
rubbish; inside this safe shelter it transforms to a brown 
pupa, which remains inactive until the following spring. 
There is but one annual generation.

The moth appears soon after the gooseberry is past 
flowering, when it deposits the eggs upon the fruit just 
formed. The wings of the moth expand nearly an inch 
across; ‘‘the fore-wings are pale gray, with dark streaks and 
bands, there is a transverse diffuse band a short distance 
from the base of the wing, enclosing an irregular whitish 
line which terminates before it reaches the front edge of the 
wing. Near the outer edge is another transverse band en-
