These two moths are classified in the Family Notodontidae and are also known as Prominents. Toothlike projections from the bottom of the lower wings are conspicuous when the moth is at rest and the wings are folded over the body like a tent. Entomologists adopted the convenient name Prominents. Not all members of this large family have obvious wing markings, but have their wings tightly rolled (cigar-style), so as to resemble tiny sticks.
Porch lights left on late at night attract these and other moths in great numbers, especially during warm summer nights.
