Pipizella nigriana

UnknownENEUENEU

Overview

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

Pipizella nigriana faces severe population declines primarily due to habitat degradation and loss of suitable breeding sites. Agricultural intensification and urban development have reduced the availability of the specific microhabitats this hoverfly requires for reproduction. Climate change may be altering the phenology of its host plants and prey species, disrupting critical ecological relationships that sustain viable populations.

Threat summary

Habitat

This hoverfly species inhabits semi-natural grasslands, woodland edges, and areas with diverse flowering plants that provide nectar sources. It requires specific microhabitats with suitable substrates for larval development and adequate prey populations to sustain adult feeding behavior.

Frequently asked questions

Why is Pipizella nigriana classified as Endangered?
Pipizella nigriana 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. Pipizella nigriana faces severe population declines primarily due to habitat degradation and loss of suitable breeding sites. Agricultural intensification and urban development have reduced the availability of the specific microhabitats this hoverfly requires for reproduction. Climate change may be altering the phenology of its host plants and prey species, disrupting critical ecological relationships that sustain viable populations.
Where does Pipizella nigriana live?
Pipizella nigriana occurs in Austria, Czechia, France, Germany, Italy, and Liechtenstein (plus 3 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 Pipizella nigriana?
The main threats to Pipizella nigriana 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.
