Patania ruralis, the mother of pearl moth, is a species of moth of the family Crambidae. It was described by Giovanni Antonio Scopoli in 1763. It is found in Europe. The caterpillar of the species is notable for its rolling locomotion.
The wingspan is 26–40 millimetres (1.0–1.6 in). The moth flies from June to September depending on the location.
The larvae feed on stinging nettle.
Scientists used the rolling behavior of the caterpillar as a model to create next-generation robots that roll.
