Greenish-yellow Oakworm Moth

Its caterpillars feed on oak foliage, so oak is central to the species' common name and life cycle. The adult moth is part of the North American saturniid group.

Dru Drury described the species in 1773. That eighteenth-century description places it among the historically documented North American moths.

No, the species is noted for sexual dimorphism, so males and females can differ visibly in appearance. The difference is one reason identification should consider sex as well as color and wing markings.

Oak trees are the most relevant place to search because the larvae feed on oak leaves. Finding caterpillars on oak is more informative than relying on the greenish-yellow adult name alone.
