Overview

Pachycnemia hippocastanaria, the horse chestnut moth, is a moth of the family Geometridae. It is found in most of Europe.

The Horse-chestnut moth is declining primarily due to habitat loss from urbanization and changes in woodland management practices. The species' dependence on specific host plants and mature woodland environments makes it particularly vulnerable to landscape fragmentation and the loss of ancient woodland sites.
