Overview

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

Nomada stigma faces significant threats from the intensification of agricultural practices and widespread use of pesticides, which directly impact both the bee itself and its host species. The species' specialized parasitic lifestyle makes it particularly vulnerable to the decline of its host bee populations, creating a cascading effect where threats to host species directly translate to threats for this cuckoo bee. Habitat fragmentation and loss of flower-rich meadows and grasslands further compound these pressures by reducing available nesting sites and foraging resources.

Threat summary

Habitat

Nomada stigma inhabits flower-rich grasslands, meadows, and woodland edges across parts of Europe, particularly favoring areas with diverse wildflower communities. As a cuckoo bee, it requires proximity to the nesting sites of its host bee species, typically in sandy or well-drained soils where ground-nesting bees establish their colonies.

Frequently asked questions

Why is Nomada stigma classified as Vulnerable?
Nomada stigma is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Nomada stigma faces significant threats from the intensification of agricultural practices and widespread use of pesticides, which directly impact both the bee itself and its host species. The species' specialized parasitic lifestyle makes it particularly vulnerable to the decline of its host bee populations, creating a cascading effect where threats to host species directly translate to threats for this cuckoo bee. Habitat fragmentation and loss of flower-rich meadows and grasslands further compound these pressures by reducing available nesting sites and foraging resources.
Where does Nomada stigma live?
Nomada stigma occurs in Algeria, Austria, Belgium, Denmark, Estonia, and Finland (plus 16 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 Nomada stigma?
The main threats to Nomada stigma 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.
