Overview

Dyscia fagaria, the grey scalloped bar, is a moth of the family Geometridae. The species was first described by Carl Peter Thunberg in 1784 and it can be found in Europe.

The Grey Scalloped Bar (Dyscia fagaria) is declining primarily due to habitat loss and degradation of its specialized woodland environments. Climate change and increased frequency of extreme weather events are also contributing to population declines by affecting the availability of its host plants and suitable breeding conditions.
