. Annual report. Entomological Society of Ontario; Insect pests; Insects. Fig. 44. The other insect referred to at the outset is called " The Forest Tent Caterpillar," Clisiocampa sylvatica, Harris. It resembles the Apple-tree Tent Caterpillar very closely in appearance at all its stages, and also to some extent in its habits. The eggs are laid in clusters (Fig. 44 a) on the twigs of "trees as in the other species, but the mass is cut square, as it were, at the ends instead of being rounded. The difference may be observed by comparing the two figures, The individual eggs are of the shape shown at Fig iid; the top is depressed and circular, as at Fig. 45. The caterpillar is also very like that of the other species in colour and appearance, but may be distinguished from it by the series of white spots along the back, which in the Apple Caterpillar are united into a continuous line. Compare Figures 45 and 42 and the difference will be plain at once. The moth (Fig. 446) resembles its congener in general colour and appearance, but may be distinguished by its paler or more yellowish colour and by the transverse bars on the wings being dark brown instead of white. Very much the same methods may be employed against this insect in all its stages, as have been recommended for the other species. The most important difference in habit is that the Forest Caterpillar spins a web against a bough or on the trunk of a tree instead of a tent in a fork, and congregates at times on the outside of the web instead of beneath it. When gathered together ki this way numbers may easily be destroyed by crush- ing them wit h a stick or pole. These insects are very voracious feeders, and if let alone.
