Extract

In the mass of literature, dealing with the fall webworm there are few references to the number of larval stadia. Bruner ( I ) states that there are four or five molts in eastern Nebraska. Dyar ( 2 ), who made measurements of the head capsules, found seven stadia. Snodgrass (3) found six larval stadia. He figures the first, second, fifth, and sixth instars.
