An all-black species with bifasciate wings. It most resembles Dipogon bifasciatus from which it may be told in the female by the shorter antenna; the third segment being about equal in length to the scape and subequal to the fourth. The male has crenulate antennae and a subgenital plate with short hairs medially.

Clearly one of the Lasioglossum calceatum group of bees, although it is fairly large for the genus, with males and females about 8 mm long. Females have mid-brown abdomens with paler apices to the segments; the males are similar, but also have red-brown markings on the anterior tergites of the abdomen. The species may abound within its very restricted range, creating very large nesting aggregations.

One of four brown bumblebees known from the British Isles, two of which, B. muscorum and B. humilis, are declining greatly. B. pascuorum, however, although it may well be less frequent than it used to be, is currently extending its range northward, being fairly recently found on Orkney. It may be seen in a great variety of habitats and is a regular inhabitant of gardens. Identification may be very difficult in the field, unless the black patches on the sides of the abdomen are well-… Read more

One of two large metallic green Lasioglossum bees in Britain. This species has a rather blue-green sheen over both the thorax and abdomen which can often be discerned in the field. Although these features often serve to distinguish it from the similarly green L. morio and L. leucopus, separation from the closely related, but more northerly and westerly distributed, L. cupromicans requires considerable… Read more
