怎样认出它

Caterpillar has a bright red head and yellow or white stripes on the body, with a black stripe along the middle of the back1
Caterpillar has bright red glands at the hind end of the back and four white, toothbrush-like tufts standing out from the back1
Caterpillar has a grey-brown hair pencil at its hind end1
Adult males are grey with wavy black lines and a white spot on the forewings1
Adult males have very feathery antennae; females have reduced wings and stay near their cocoon1

常被误认为： The vapourer (Orgyia antiqua) is similar to the adult male but is a rusty colour rather than grey.1

事实

The four white tufts on the caterpillar's back may mimic the cocoons of parasitic wasps.1

Large caterpillars are mostly eaten by birds, while small caterpillars mostly disappear while dispersing.1

The fungus Entomophaga maimaiga was introduced to North America to control the spongy moth, and it also infects this species.1

There are two or more generations each year in eastern North America, and the eggs overwinter.1
