206 SPAN-WORMS. 
fectly quiet for a time, and resemble the twigsso thoroughly 
that is very difficult to detect them. When they are full 
grown they hide in some shelter, and thus pass the winter; 
early in spring they leave their hiding places and after eat- 
ing for a few days they transform to pupz and soon after- 
wards to moths. 
At present these caterpillars are found most abundantly 
in places where wild grapes are growing, but they are by no 
means strangers to our vine-yards, where they eat a large 
amount of foliage, thus sometimes causing some slight in- 
jury. Being so well protected by shape, color and position 
they may be very common on our vines, yet are not recog- 
nized. 
THE CURRANT FRUIT WORM. 
(Eupithecia interrupto-fasciata Pack.). 
This is not acommon moth, at least it is not often found 
in our gardens. But the fruit of wild currants frequently 
show its presence, or rather that of the worms. These are 
about five-eighths of an inch long, and very variable in col- 
oration and markings. Their bodies are 
usually of a pale-ash or yellowish-green color, 
with a dark line down the back and another 
one on each side, which is, however, frequently 
' absent. In some cases there is a row. of dark- 
colored lozenge-shaped spots along the dorsal 
Fig.200.—Eupi.line, and a second lateral line lower down. 
fassiatg back, The terminal segment carries two short green- 
ish lines; the under side of the body is pale-greenish 
and almost white, with a yellowish line in the middle. 
The head varies from yellowish or greenish to light brown. 
When full grown the caterpillar draws together a number 
of leaves and other material, fastens them with silken 
threads, and in this shelter changes to a pupa and later 
toa moth.
