It was in Tas. Out along Waterfall Bay track. Thanks for the name, gave me something to search with.
From NSW Office of Environment & Heritage:
NSW Scientific Committee - final determination
The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the Introduction of the Large Earth Bumblebee, Bombus terrestris (L.), as a KEY THREATENING PROCESS in Schedule 3 of the Act. Listing of key threatening processes is provided for by Part 2 of the Act.
1. The Large Earth Bumblebee, Bombus terrestris (L.) (Hymenoptera: Apidae), is a relatively large, primitively eusocial bee native to Europe. Bombus terrestris is generally more heavily built and hairier than the honeybee, Apis mellifera L.. Large Earth Bumblebee queens are 30-35mm long; workers are more variable in size, ranging from 8-22mm long; and males are similar in size and appearance to large workers. Large Earth Bumblebees are black with one yellow or ochre band across the front of the thorax and a second yellow or ochre band across the abdomen. The tip of the abdomen is either buff or white.
2. In cool climates Large Earth Bumblebees form annual colonies and new colonies are initiated each spring by mated solitary queens. Colonies quickly reach sizes of 300 to 500 individuals. In warmer areas colonies may reach large sizes, with colonies of more than 1000 individuals being recorded in Tasmania (Buttermore 1997).
3. Large Earth Bumblebees were first recorded in Tasmania in 1992 and have since spread over a large area of the state in both urban and native bush areas (Hingston et al. 2001). This species of bumblebee forages from a wide range of plant species. In Tasmania it has been recorded foraging from at least 170 plant species (156 exotic, 14 native; Semmens 1996) and in New Zealand it has been recorded visiting 400 species of exotic plants (Low 1999).
4. Colonies of Large Earth Bumblebees have become established throughout Tasmania in a wide range of habitats from sea level to 1250m altitude within all the major native vegetation types (Hingston and McQuillan 1998).
Most interesting - I have also found them in the backyard.
