Overview

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

Xerarionta intercisa faces severe habitat degradation from urban development and agricultural expansion across its limited range in southern California. The species is particularly vulnerable to drought conditions and altered fire regimes that affect the coastal sage scrub and chaparral communities it depends upon. Invasive plant species further degrade habitat quality by outcompeting native vegetation that provides essential shelter and food resources.
