tent caterpillar, common name for the larvae of the members of a family of moths (Lasiocampidae), easily recognized by the large silk tents, or webs, that the larvae construct during the spring in the crotches of trees, particularly apple and cherry trees.
The tent caterpillar pupates within the oval white cocoon it spins, and the adult emerges during midsummer as a reddish brown or gray, medium-sized, stout-bodied, hairy moth with feathery antennae.
Tent caterpillars are classified in the phylum Arthropoda, class Insecta, order Lepidoptera, superfamily Bombycoidea, family Lasiocampidae.
