The larvae feed on various woody plants, including coontie, cabbage palmetto, crotons, lupine, oak and persimmon.[3]
Caterpillars
At Stetson University's DeLand, FL campus, many of the Seirarctia echo can be seen in their caterpillar stage. Colloquially referred to as "Haterpillars[4]" (a reference to the school mascot), these caterpillars are well known by students due to their frequent sightings in the summer, fall, and late spring. Although less frequent, the moths are also occasionally spotted.
