The forest tent caterpillar moth (Malacosoma disstria) is a moth found throughout North America, especially in the eastern regions. Unlike related tent caterpillar species, the larvae of forest tent caterpillars do not make tents, but rather, weave a silky sheet where they lie together during molting .
Immediately after feeding the caterpillars return to the tent and aggregate in sunlight to facilitate the digestive process. Thus, eastern tent caterpillars are central place foragers. In contrast, the forest tent caterpillar is a nomadic forager that establishes a series of temporary resting sites during the course of its larval development.
Larvae feed on leaves, often defoliating affected branches. Pacific tent caterpillars spin rudimentary tents that can be up to 10 cm (3.9 in) wide. The larvae feed in groups outside the tent, entering it only to molt. [2] Pacific tent caterpillars have speckles on the sides, orange hairs on top and grayish or cream colored hairs on the sides.
In tent caterpillars, the eggs are deposited in masses and covered with a material that hardens in air. Females are generally larger and slower than the males, but the sexes otherwise resemble each other. Moths are typically brown or grey, with hairy legs and bodies. A family of moths mostly of large size.

Malacosoma californicum, the western tent caterpillar, is a moth of the family Lasiocampidae. It is a tent caterpillar. The Western Tent Caterpillar is found in southern Canada, the western United States, and parts of northern Mexico. There are currently six recognized subspecies of M. californicum. [1]
Bag of Metura elongatus which can grow to more than 120 mm (4.7 in) in length Bagworm moth caterpillar locomotion. The Psychidae (bagworm moths, also simply bagworms or bagmoths) are a family of the Lepidoptera (butterflies and moths). The bagworm family is fairly small, with about 1,350 species [2] described.
North American moths represent about 12,000 types of moths. In comparison, there are about 825 species of North American butterflies. The moths (mostly nocturnal) and butterflies (mostly diurnal) together make up the taxonomic order Lepidoptera. This list is sorted on MONA number (MONA is short for Moths of America North of Mexico).
