Overview

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

Dasysyrphus nigricornis faces severe habitat loss as Arctic and subarctic forests experience rapid warming and altered precipitation patterns. Climate change is shifting the species' specialized boreal forest habitat northward faster than the hoverfly can adapt, while logging activities fragment remaining suitable woodland areas. The species' dependence on specific host plants and microhabitat conditions makes it particularly vulnerable to environmental changes.

Threat summary

Habitat

This Arctic hoverfly inhabits boreal and subarctic coniferous forests, particularly areas with dense understory vegetation and specific flowering plants. The species requires cool, humid microhabitats within northern woodlands where it can complete its lifecycle tied to particular host plant species.
