ON THE NUMBER OF MOLTS IN LARVAE OF THE FALL WEBWORM, HYPHANTRIA CUNEA DRURY. (LEP. ARCTIIDAE)
Published online by Cambridge University Press: 31 May 2012
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.
