Overview

Lasioglossum zonulus is a species of sweat bee in the family Halictidae. It is found in Europe and North America. While the name has historically been misspelled "zonulum", the original name, zonulus, is a noun and does not change spelling under Article 31 of the ICZN, and some sources have recognized this and adopted the correct spelling.

The Bull-headed Sweat Bee faces severe population declines primarily due to habitat loss from urban development and agricultural intensification in its limited range. Climate change and the use of pesticides in agricultural areas further threaten the remaining populations of this specialized bee species.
