Lasioglossum smeathmanellum

Without a sample and examining under a microscope this is not a 100% ID

Restricted to southern England, Channel Islands, Wales and north to Northumberland. It is gradually replaced by the closely related L. cupromicans towards the north, and in upland situations, particularly in the South-west. The species has a generally Mediterranean and Atlantic distribution in Europe. It is also known from north Africa.

Status (in Britain only)
This bee is not regarded as being scarce or threatened. However, the species does seem to have declined nationally in recent years (G R Else, pers. comm. & M Edwards, pers. obs.).

Although L. smeathmanellum may be encountered almost anywhere in southern England and Wales, it is often abundant on coastal soft-rock cliffs. Inland it is frequently reported as nesting in the soft mortar of old walls.

Flight period
Females fly between late March and September, males are found between July and September. As with all British Lasioglossum, only mated females hibernate.

Pollen collected
This species is polylectic.

Nesting biology
Often nests communally in suitable areas of old walls and bare cliffs, but is not known to be eusocial, with a queen and a few workers.

Flowers visited
Recorded visiting a wide variety of flowers from a number of different plant families…BWARS
