The 'Rough Prominent' ('''Nadata gibbosa''') is a
moth of the family
Notodontidae, possibly in the
subfamily Notodontidae. It is also known as the 'White-dotted Prominent' and the 'Tawny Prominent'. This common moth is found across
North America from the northern
boreal forests to as far south as
Florida. It is most common in
deciduous forests at some elevation. It is
nocturnal but attracted to lights. 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. They then pupate until the following spring.
The moth is tan or dull orange in color, with two small silver spots on each forewing. The
wingspan is approximately 2 inches. It sports a pointed
thoracic tuft between its wings.
The larva is blue-green, turning bright green as it approaches pupation age. It has a large head capsule, yellow mandibles, and yellow longitudinal stripes down its body. It feeds on the leaves of
oaks and other deciduous trees (see list below). The larva is sometimes called the 'green oak caterpillar'.
