Grammia incorrupta

Grammia incorrupta is an arctiine moth in the family Erebidae, described by Henry Edwards in 1881. It is found from southern Colorado and south-eastern Kansas south through Arizona, New Mexico and western Texas into Mexico and west to south-eastern California. The habitat consists of grasslands and open woodlands.

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.

The larvae feed on a wide range of herbaceous, flowering plants, including Fallugia paradoxa.

Recent research 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".
