For details see Williams Bumblebees of the World
A rather local lowland species of bumble bee which has shown a significant decline in range in recent years. Identification keys and general biology are found in Sladen (1912), Free & Butler (1959), Alford (1975) and Prŷs-Jones & Corbet (1991). A very rare melanic form, f. nigrescens, was found a few times in East Sussex in the 1920s. Darker specimens were found again in 2011 on Dungeness (N Gammans pers. comm) and at Deal (RL Evans & ED Moss, pers. comm)
Formerly locally frequent in England, south and east of the Severn-Wash line with scattered records from lowland areas over the rest of England, coastal areas of Wales and scattered localities in lowland Ireland. Since the 1960s this species has shown a severe reduction in range. In 1999 there were only seven areas with known populations of this bumblebee: four in England and three in South Wales. There are a few modern records for the Burren, Ireland. The species ranges through most of Europe except the northern parts of Scandinavia and the Mediterranean area eastwards to the Urals.
