Hormopeza obliterata

Local name: rökdansfluga

Unknown

Overview

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

Hormopeza obliterata faces severe population decline primarily due to habitat destruction from urban development and agricultural expansion across its limited Scandinavian range. The species' specialized requirements for old-growth forest microhabitats make it particularly vulnerable to logging operations and forest fragmentation. Climate change poses an additional threat by altering the moisture and temperature conditions essential for its survival and reproduction.

Threat summary

Habitat

This specialized dance fly inhabits mature coniferous and mixed forests, particularly favoring areas with high humidity and dense canopy cover. The species requires specific microhabitat conditions found in old-growth forest environments with abundant decaying organic matter and stable moisture levels.
