Taxonomic group: honey bee and bumblebees (Aculeata: Apinae) - Part county data
Bombus ruderarius is a nationally declining species which at the time of publication of the Bumblebees of Essex (Benton, 2000) was still considered to be widespread, but local, in the county. However current evidence suggests a drastic decline has occurred, with sites where the bumblebee used to occur in numbers a few years ago now apparently without populations. Like other declining bumblebees, the species requires extensive areas which support a variety of flowering plants, especially Fabaceae and Lamiaceae, and it is essential that suitable forage resources are available throughout the flight period of the colony. The nest is constructed of grass clippings and moss on or just above the ground among long vegetation, often using an old mouse nest as a foundation (Edwards & Telfer, 2001). References
