Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Euproserpinus wiesti faces severe threats from habitat destruction due to urban development and agricultural expansion in its limited California range. The species' specialized relationship with its host plant, Clarkia, makes it particularly vulnerable to habitat fragmentation and degradation. Climate change poses additional risks through altered precipitation patterns that could affect the timing of host plant availability and larval development cycles.
