Lantaarnsponsgaasvlieg

Sisyra terminalis

Unknown

Overview

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

Sisyra terminalis faces significant threats from freshwater habitat degradation and pollution, as its larvae are entirely dependent on clean aquatic environments where they parasitize freshwater sponges. Water quality deterioration from agricultural runoff, urban development, and industrial discharge directly impacts both the host sponges and the neuropteran larvae. Climate change-induced alterations to freshwater ecosystems, including temperature fluctuations and altered precipitation patterns, further compromise the delicate ecological relationships this species requires for reproduction and development.

Threat summary

Habitat

This neuropteran species inhabits clean freshwater environments including streams, rivers, and lake margins where freshwater sponges are abundant. The larvae are aquatic and live as ectoparasites on freshwater sponges, while adults are found in riparian vegetation near these water bodies.
