eral short prickles. Like some closely allied caterpillars this 
one has the habit of disguising itself by attaching to the 
thorny prickles upon its body tiny bits of vegetable matter, 
such as the anthers of flowers, and by this means it often 
escapes detection. It makes a slight cocoon, and changes to 
a pupa of a yellow color with darker lines and spots, from 
which soon afterward emerges the perfect insect. The dif- 
ferent states of this insect are shown in Fig. 183. 
Besides the raspberry, the caterpillar also occurs upon 
the fruit of the blackberry. 
It is not likely that this insect will ever become very 
destructive. If it does we can not depend upon any poison- 
ous insecticides, as otherwise the fruit could not be used, but 
have to resort to hand-picking. 
THE ABORTIVE DYSPTERIS. 
(Dyspteris abortivaria H.S.). 
This green moth is closely allied to the Synchlora. It 
expands about seven-eighths of an inch, and is of a pale- 
green color, with two oblique parallel white lines running 
through both wings. The moth can be recognized at once 
from all other similar colored ones by the great difference in 
size existing between the fore and hind-wings, the former

being rather large, while the latter are not more than half 
as large as might be expected when compared with other 
moths of the same genus. The moth is not very common. 
It is shown in Fig. 184.
