Mocis

Mocis is a genus of moths in the family Erebidae. The genus was erected by Jacob Hübner in 1823.

Lepidopterist David Wagner et al. state about the behaviour of Mocis larvae: "Unlike most catocaline larvae, Mocis caterpillars do not wriggle violently when accosted, but rather simply drop to the ground--a habit shared by many grass feeders--where their coloration blends in with dead, withered grass blades."
