Often times they are- attacked by a small Ichneumon fly, and when caterpillars dead from this cause are observed it is well not to disturb them. They are much shortened, grayish in color, and the cocoon of the contained parasite gives them a characteristic bloated appearance.

The caterpillar of this butterfly is one of the most commonly observed defoliators of the elm, and is sent to this station a large number of times ever}' season by persons mistaking it for the cater- pillar of the Gypsy Moth, to which, however, it bears only a slight superficial resemblance. There are two broods of this insect in JNIassachusetts, the butter- flies from the first appearing late in J line or early in July, and from the second in the fore part of September. Those of the second brood hibernate and appear again on the wing at the first approach of spring, and by the middle of May have laid the eggs for the first brood. The pale yellow, ribbed, barrel-shaped eggs to the number of about 200 are laid in a single layer about a terminal twig of the food plant,, and hatch in about a week from the date of Fig. 11.—Antiopa Butterfly Caterpillar. (After Scudder.).
