Because it is a beneficial colonial kinds that’s productive throughout the growing year, their number one specifications are a series of pollen and you can nectar supplies in the springtime and you will june (Goulson 2010). The fresh productive 12 months is roughly April to help you Sep from the southern area area of the Reddish-banded Bumble Bee’s assortment and will-ount away from foraging info are continuously one variable in the Yellow-banded Bumble bee environment solutions (Liczner and Colla 2020). Some of the plant life made use of are thought intrusive otherwise exotic weeds in disturbed habitats (age.grams., Light Nice-clover, Melilotus alba; Preferred Dandelion, Taraxacum officinale; White Clover, Trifolium repens).

Regarding late summer and early autumn (late July throughout the northern, August and you can very early September from the south), reproductive mature lady and you may guys come out of the newest nest and leave to get mates. Mated women disperse to pick an overwintering site, travelling an unknown range to accomplish this. 2014, COSEWIC 2015). The particular overwintering habitats away from Yellow-banded Bumble-bee queens is actually unfamiliar (Liczner and you will Colla 2019), but bumble bees normally burrow 2-15 cm deep within the sagging surface or decaying logs (Macfarlane 1974; Benton 2006; Liczner and Colla 2019). Due to the fact queens do not survive one or more wintertime around isn’t any overwintering webpages fidelity because of the somebody.

Dispersal occurs mostly within the spring by the queens whenever you are looking appropriate colony internet sites (Goulson 2010). You will find facts one bumble bees can circulate relatively much time distances, about ranging from 2.6 and you can ten kilometer about colony from source (Stout and you can Goulson 2000, Kraus et al. 2008, Lepais mais aussi al. 2010).

Yellow-banded Bumble Bees nest underground (Laverty and you can Harder 1988), usually in the given up rat otherwise bunny burrows (Plath 1927; Hobbs 1968; Macfarlane 1974; Colla and Dumesh 2010).

step three.4 Restricting items

Bumble bees has actually a variety of sex commitment that renders them most susceptible to extinction whenever energetic populace models try short (Zayed and you may Packer 2005). Once the amounts refuse, more info on female write as sterile males as an alternative. Inside basic terms, when the a beneficial bee society decreases for some recreating individuals, you can be assured to be in your town extirpated also lower than beneficial ecological criteria unless the matter develops inside several years. There are not any research with the need for this matter within the Canadian Red-colored-banded Bumble-bee communities at the moment, but (like) it would most likely reduce ability of your types in order to recolonize significant southwestern Ontario.
