Halictus rubicundus

Halictus rubicundus is a species of sweat bee found in Europe and North America.

Its breeding behaviour differs depending on climate - it is a solitary species in cooler regions, but is a social breeder in warmer areas.

H. rubicundus nests are constructed in the ground. Nests are dug in spring by a single female who typically rears a brood of 5-7 offspring. The nest entrance is about 5 mm in diameter and, occasionally, a small pile of soil accumulates outside the entrance as a result of the female's excavations.
