Agrotera nemoralis, the beautiful pearl, is a species of moth of the family Crambidae.

The rather similar Agrotera posticalis, described from Japan, instead of a synonym is often treated as a valid species.

This widespread species can be found from Europe to India, China and Japan.

Forewings are brown with an orange reniform spot and a clear band with an irregular post median line.

The larvae feed on leaves of Carpinus betulus, but are also spotted on hazel, birch and chestnut.
