UnknownLCEULCEU

Overview

The kortspriet korsetzweefvlieg (Neoascia geniculata) is a small hoverfly species characterized by its distinctive short antennae and yellow-black banded abdomen with a characteristic 'corseted' appearance. Adults are important pollinators of wildflowers, while their larvae develop in decaying organic matter, contributing to nutrient cycling in wetland ecosystems.

Neoascia geniculata is declining primarily due to habitat loss and degradation of wetland ecosystems across its European range. Agricultural intensification, urban development, and changes in water management practices have significantly reduced the availability of suitable breeding and foraging habitats for this specialized hoverfly species.

Threat summary

Habitat

Neoascia geniculata inhabits reed beds, wet meadows, and marshy areas with slow-moving or standing water where organic matter accumulates. The species requires proximity to diverse flowering plants for adult feeding and specific water chemistry conditions for larval survival in semi-aquatic environments.

Frequently asked questions

Why is kortspriet korsetzweefvlieg classified as Endangered?
kortspriet korsetzweefvlieg is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Neoascia geniculata is declining primarily due to habitat loss and degradation of wetland ecosystems across its European range. Agricultural intensification, urban development, and changes in water management practices have significantly reduced the availability of suitable breeding and foraging habitats for this specialized hoverfly species.
Where does kortspriet korsetzweefvlieg live?
kortspriet korsetzweefvlieg occurs in Åland Islands, Austria, Belgium, Canada, Denmark, and Estonia (plus 10 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to kortspriet korsetzweefvlieg?
The main threats to kortspriet korsetzweefvlieg are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
