Overview

Diasemia reticularis is a species of moth of the family Crambidae. It is typically found in the tropics, but may range into Europe as far north as the North Sea region because of its migratory nature.

The Lettered China-mark moth is declining primarily due to habitat loss and degradation of its specialized wetland environments. Water pollution, agricultural intensification, and drainage of wetlands for development have severely reduced the availability of suitable breeding sites where its aquatic larvae can develop.
