02Description

Species Profile

Dufourea inermis is a small, solitary sweat bee species characterized by its metallic green-black coloration and compact build. This ground-nesting bee plays a crucial ecological role as a specialized pollinator of native wildflowers, particularly those in the sunflower family, contributing to the reproductive success of numerous plant species in its ecosystem.

Dufourea inermis faces severe population declines primarily due to habitat loss from agricultural expansion and urban development in its limited range. Climate change and pesticide use in agricultural areas further threaten remaining populations of this specialized bee species.
