Overview

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

The Manchester Treble-bar faces severe habitat loss due to urban development and industrial expansion across its limited range in northwestern England. Climate change poses an additional threat by altering the specific temperature and humidity conditions required for its host plants and larval development. The species' extremely restricted distribution makes it particularly vulnerable to local environmental changes and pollution from nearby industrial activities.
