Bombus hortorum (Linnaeus, 1761)
length queen 17 to 22 mm, male 13 to 15 mm, worker 11 to 16 mm.
Also called the ‘Long-tongued Bumblebee’, it has two yellow bands on the thorax, one yellow band on the abdomen, and a white tail. The tongue is very long (the longest of any bumblebee found in Europe, in fact), and the male has black facial hairs. Despite the vernacular name, it is a large species, and scruffy looking.
The nests are usually made underground and always under cover. Queens searching for suitable nesting sites may be observed March to May. Mature nests contain around 100 workers. Barbut’s Cuckoobee (Bombus barbutellus) takes over the nests of B. hortorum, of which it looks very similar, but it is not nearly as widespread.
The males appear in June, and they are found in many habitats, especially gardens. They regularly visits foxglove (Digitalis), Red Clover (Trifolium pratense), and Dead-nettle (Lamium). A widespread and abundant species.
