Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Bombus quadricolor faces significant population declines primarily due to habitat loss from agricultural intensification and urban development across its European range. The species is particularly vulnerable to the widespread use of neonicotinoid pesticides, which impair foraging behavior and colony development. Climate change poses an additional threat by altering the timing of flower blooms relative to the bee's emergence, disrupting critical pollination relationships.
Habitat
This bumblebee species inhabits flower-rich grasslands, meadows, and agricultural landscapes across temperate Europe. It particularly favors areas with diverse wildflower communities and requires suitable nesting sites in abandoned rodent burrows or grass tussocks.
