The eastern tent caterpillar (1935) The eastern tent caterpillar easterntentcater00brit Year: 1935 70 Connecticut Experiment Station Bulletin 378 covers them with a viscid fluid which hardens, giving them a varnished appearance. Probably this coating is a great protection against the weather and predaceous insects. (See Figures 5 and 12.) The eggs do not hatch until the following April, thus remaining upon the twigs for about nine months. The tiny caterpillars first feed upon the frothy mass surrounding the eggs, and next attack the new leaves which are then unfolding. After a few days they spin many silken threads to form their nest, usually in a fork of the branches. (See Figures 6, 7 and front page of bulletin.) Each nest, or colony, contains the caterpillars from a single cluster of eggs. In fair weather the insects feed in the morning and again in the afternoon, and, according to Fitch, again at night; but during cloudy weather they remain in the nest. In 1935, Mr. M. P. Zappe of this department examined infested chokecherry bushes several times between dusk and midnight and always found the caterpillars in the nest. When nearly full grown, the caterpillars may often be found at rest on the out- side of the tent, as shown in Figure 1. They spin threads wherever they crawl along the branches fromjthe nest to their feeding places. Figure 5. Egg-cluster, natural size.
