hippupalkonen

Hydroptila simulans

Unknown

Overview

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

Hydroptila simulans faces significant pressure from water pollution and eutrophication in its freshwater habitats, which degrades the water quality essential for its larval development. Agricultural runoff containing pesticides and fertilizers poses a particular threat to this caddisfly species, as it disrupts the delicate aquatic ecosystems where larvae construct their characteristic cases. Climate change-induced alterations to stream flow patterns and temperature regimes further compromise the species' ability to complete its complex life cycle.

Threat summary

Habitat

This caddisfly species inhabits clean, well-oxygenated freshwater streams and rivers with rocky or sandy substrates. The larvae require specific water quality conditions and construct protective cases from sand grains and organic matter while feeding on algae and detritus.
