At Stetson University's DeLand, FL campus, many of the Seirarctia echo can be seen in their caterpillar stage. Colloquially referred to as "Hatterpillars<ref>{{cite tweet |author=Stetson University |user=StetsonU |number=311499280651259904 |date=March 12, 2013 |title=They're baaaaack...

Although less frequent, the moths are also occasionally spotted.
