The length of the forewings is about 18.6 mm. The hindwings are pink to yellowish pink. There are two generations per year with adults on wing from late April to early October.[2]
The larvae feed on a wide range of herbaceous, flowering plants, including Fallugia paradoxa.[3][4]
Recent research[5] has shown that the larvae of Grammia incorrupta consume alkaloid-laden leaves that help fight off internal parasitic fly larvae. This phenomenon is said to be "the first clear demonstration of self-medication among insects".
This species was formerly a member of the genus Grammia, but was moved to Apantesis along with the other species of the genera Grammia, Holarctia, and Notarctia.[6][7]
