REPORT OF THE STATE ENTOMOLOGIST 1918 157 
The peculiar, whitish masses of pitch (fig. 29) caused by this 
species are easily recognized. They may hang from the underside 
of the limbs and occasionally occur in considerable numbers on the 
trunk of pitch pine. There is frequently a dripping of the pitch in 
warm weather. 
Observations by Miss Eckel show that the bright orange larvae 
are arranged radially about the equator of a spherical pitch drop. 
The eggs are deposited only on fresh pitch 
and never on twigs or leaves, the insect 
apparently taking advantage of fresh ex- 
udations and, as a rule, finding them in 
abundance. The young larvae grow rapidly 
and in the early stages have hooklike spines 
on the ventral surface of each segment. 
These disappear and the entire skin is cov- 
ered with fine, backward curving spines. 
We reared adults the latter part of June and 
in early October from material which was 
supposed to represent only the work of 
the pine twig moth, Evetria com- 
stockiana Fern. The normal pitch 
mass inhabited by this midge may contain 
from two to thirty larvae which, when full 
grown, are about 6 mm in length. The 
pupa works its way partly out of the pitch © m2 
mass before the appearance of the midge. ee) Ean cus
