Overview

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

The Saltern Marble faces severe habitat loss due to coastal development and saltmarsh destruction across its limited range in southern England. Rising sea levels and increased storm frequency threaten the specialized saltmarsh environments this species depends upon. Agricultural intensification and water management changes have altered the hydrology of remaining coastal wetlands, reducing the quality of breeding habitats.

Threat summary

Habitat

This moth species inhabits coastal saltmarshes and brackish wetlands along the southern English coast, particularly areas with dense stands of sea aster and other halophytic plants. The larvae feed specifically on saltmarsh vegetation, requiring the unique conditions found in tidal marsh ecosystems.
