Eastern Tent Caterpillar Gallery

Eastern Tent Caterpillar


Before trees leaf out in the spring is a good time to look for eastern
tent caterpillar egg masses on twigs; prune off branches when possible.

Early instar caterpillars are clustered on the silk tents;
tents are found in tree crotch angles.


This late instar eastern tent caterpillar will be looking for
a place to pupate soon.


Crabapples are a common host for eastern tent caterpillars;
also check cherries.
