Bombus pratorum

Early bumblebee

It is one of the smallest and earliest bumblebees to appear each year, often finishing its whole colony cycle before larger species are in full swing.

WhenMarch to August

A small, neat bumblebee with a bright orange red tail and a yellow band on the thorax and another near the base of the abdomen, sometimes faded or missing in workers.

Colonies are short lived compared with other bumblebees, running from spring to midsummer, which is why this species is rarely seen much past July or August.
