Local name: reliktslända

Unknown

Overview

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

Inocellia crassicornis faces severe threats from habitat fragmentation and loss of old-growth coniferous forests across its limited Scandinavian range. Climate change poses an additional risk by altering the cool, humid microhabitats essential for this relict species' survival. The species' extremely restricted distribution and specialized ecological requirements make it particularly vulnerable to environmental changes and human disturbance.

Threat summary

Habitat

This relict snakefly inhabits old-growth coniferous forests, particularly those dominated by spruce and pine, where it requires cool, humid microclimates with abundant dead wood and bark crevices. The species is found in montane and boreal forest ecosystems across limited areas of Scandinavia.
