Wormaldia occipitalis

Unknown

Overview

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

Wormaldia occipitalis faces significant threats from water pollution and habitat degradation affecting the clean, fast-flowing streams it requires for larval development. Agricultural runoff, urban development, and industrial activities have compromised water quality in many of its known locations. Climate change poses additional risks through altered precipitation patterns and increased water temperatures that could disrupt the delicate aquatic ecosystems this caddisfly depends upon.

Threat summary

Habitat

Wormaldia occipitalis inhabits clean, fast-flowing streams and rivers with rocky substrates where larvae can attach and feed on organic matter. Adults are typically found near these aquatic habitats, often in forested or semi-forested areas that provide suitable conditions for mating and egg-laying.
