The rough prominent (Nadata gibbosa) is a moth of the family Notodontidae, subfamily Phalerinae.

This common moth is found across North America from the northern boreal forests to as far south as Florida.

The moths start to fly soon after dusk and return to resting places some time before dawn breaks (Fullard & Napoleone 2001).

The adults live through late spring and early summer, and larvae are active until fall.

The moth is tan or dull orange, with two small silver spots on each forewing.
