Overview

Leptidea juvernica, the Cryptic wood white, is a butterfly in the family Pieridae.

The Cryptic Wood White is critically endangered primarily due to habitat loss and fragmentation of its specialized woodland and grassland habitats. Agricultural intensification, urbanization, and changes in land management practices have severely reduced the availability of suitable breeding sites and host plants. Climate change may also be affecting the species' distribution and the phenology of its host plants.
