Food plant choice varies by species and is dictated by tongue length. Larvae feed on pollen gathered by the adults. Adults feed on nectar from native wildflowers and crops for energy to fuel flight. ( Colla, et al., 2011)īumble bees consume the nectar and gather the pollen of a wide variety of plants. Like other bees, bumblebees can see ultraviolet light. Bees communicate about the safety of the nest, where food is, and what they should do. Like other social bees, bumblebees communicate using touch, vision, chemicals called pheromones, and wing vibrations. ( Colla, et al., 2011 Eaton and Kaufman, 2007 Resh and Cardè, 2009) Bumble bees are active for an oddly long part of the year. In the nest, pollen and saliva are chewed together to produce honey. While bees hunt for nectar and pollen, they pollinate the plants that they land on. Older generations of bumble bees hunt for pollen during the day. Younger generations take care of the larvae. ( Colla, et al., 2011 Eaton and Kaufman, 2007 Resh and Cardè, 2009)īumble bees can live in surprisingly large groups. In the nest, pollen and saliva are combined to produce honey to feed the colony. While bees forage, they pollinate the plants from which they harvest pollen and nectar. Older generations forage for pollen during the day while younger generations care for the brood. Bumble bee queens live with their male and female offspring. Social and colonial, bumblebees can form large colonies. In areas that do not get cold seasons, bumble bees may be found year-round. Workers and males live for a much shorter time period, typically dying with the onset of colder weather. Queen bumble bees live for a maximum of one year. ( Colla, et al., 2011 Stange and Fasulo, 2018)īumble bees produce annual generations. Members of this genus utilize female parental care. ( Bartlett, 2019 Colla, et al., 2011 Stange and Fasulo, 2018) Males are typically produced during midsummer. The first brood of worker bees hatches and they care for the next generation. After fertilized queens emerge from overwintering in the spring, they will build the colony alone. ( Colla, et al., 2011)Ĭolonies of bumble bees are annual and are founded by a single queen bee. This subgenus is made up of social parasites that utilize the nests of other bumble bees to produce offspring. ( Colla, et al., 2011)īumble bees are eusocial, except for members of the subgenus Psithrys. Pupae develop for an additional 2 weeks before emerging. They spin cocoons and pupate in about two weeks. Larvae go through four instars of development. ( Borror and White, 1970 Colla, et al., 2011 Stange and Fasulo, 2018)Įggs are laid in individual cells and hatch after approximately 4 days. Bumble bees can be differentiated from eastern carpenter bees by the pubescence on the dorsum. Members of this genus can be confused with eastern carpenter bees. Species of bumble bees have varying tongue lengths. Males and females of some species have differing facial colors, which allows them to be differentiated. Females have corbicula (pollen baskets) on their hind tibiae. They have short, pale yellow hairs on their thoraxes and black hairs on their heads, abdomens, and legs. Some species have orange or reddish colors too. ( Colla, et al., 2011 Resh and Cardè, 2009 Stange and Fasulo, 2018)īumble bees have a distinctive yellow and black striped pattern. Others may steal nests from other bumble bees. Some species of this genus may create nests underground. Bumble bees can be found in cold temperate to warm subtropic climates. Grasslands, forests, and marshes are also habitats of this species. ( Colla, et al., 2011)īumble bees inhabit a broad habitat, including urban areas, suburban locations, and farmlands. They are not found in Australia, parts of India, and most of Africa. ( Bartlett, 2019 Colla, et al., 2011) Geographic Rangeīumble bees are found in the temperate regions of North, Central, and South America, Europe, and Asia. In North America, there are 43 species in the west, 24 in the east, and 18 in the south. The genus Bombus, commonly known as bumble bees, includes 260 species worldwide.
