Lasioglossum boreale

Local name: fjällsmalbi

UnknownDDEU

Overview

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

Lasioglossum boreale faces significant pressure from climate change as warming temperatures alter the alpine and subalpine environments it depends on. Habitat fragmentation from infrastructure development and tourism activities in mountainous regions further restricts available nesting sites. The species' specialized pollination relationships with arctic-alpine flora make it particularly vulnerable to phenological mismatches caused by shifting seasonal patterns.

Threat summary

Habitat

This specialized bee inhabits alpine and subalpine meadows, typically above 1,000 meters elevation in Scandinavia's mountain regions. It nests in well-drained soils near flowering plants adapted to harsh northern climates, particularly favoring areas with sparse vegetation and exposed mineral soil.

Lasioglossum boreale faces significant pressure from climate change as warming temperatures alter the alpine and subalpine environments it depends on. Habitat fragmentation from infrastructure development and tourism activities in mountainous regions further restricts available nesting sites. The species' specialized pollination relationships with arctic-alpine flora make it particularly vulnerable to phenological mismatches caused by shifting seasonal patterns.
Where does fjällsmalbi live?
fjällsmalbi occurs in Canada, Finland, Greece, Italy, Norway, and Russia (plus 3 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
