...Trifolium pratense and Echium vulgare have been noted as the predominant plant species visited by the long-tongued species (Goulson & Hanley 2004) along with Lupinus spp. for B. subterraneus (Donovan 2007)....

...Bombus subterraneus appears restricted to the central South Island (Macfarlane & Gurr 1995), particularly around lake margins (Goulson & Hanley 2004; Goulson et al. 2006) and the population may be declining (Howlett et al. 2009b)....

...Its willingness to forage on more plant species, and over a greater geographic range, allows a greater exploitation of habitat types compared with the longtongued species (Goulson & Hanley 2004)....

...Indeed, the success of British bumblebees in New Zealand must have been greatly facilitated by the similar climate in many parts of New Zealand and the presence of an abundance of introduced bumblebee forage plant species (Hanley & Goulson 2003; Goulson & Hanley 2004; Lye et al. 2010)....

...4) and the subsequent existence of this species within relatively small populations (Goulson & Hanley 2004; Lye et al. 2010), it might have been predicted that genetic diversity would be low and that similarity to the original British population is likely to be limited, and this is indeed the case....

...In addition to T. pratense and L. corniculatus, both of which are highly dependent on insects for pollination (Grime et al., 1988), we found substantial numbers of bumblebees visiting lupin (Lupinus arboreus and L. polyphyllus), thistles (Cirsium vulgare), and broom (Cytisus scoparius)....

...Although H. perforatum is believed to be increasing in abundance in the U.K., the other main forage plants we identified in New Zealand (E. vulgare, L. corniculatus and T. pratense) are all declining (Grime et al., 1988; Rich and Woodruff, 1996)....
