![]() Living underground allows them to avoid overheating and direct sunlight nests in temperate regions will only last one season. The bumble bee is a social bee and lives in an underground colony which can hold as few as 50 bumble bees the colony is not large like a honey bee colony. Pollinating Honey Bee Behavior of Large Black Beesīoth of these bees have extremely different behavior. Carpenter bees could be the problem if you're seeing big black bees near your home. In addition, carpenter bees can cause damage to your home if they nest in the wood. This avoids the transferring of pollen all together. These black bees are known for robbing pollen from plants by creating a hole near the base of the flower to easily access the nectar. On the other hand, carpenter bees are not strong pollinators. Currently, the pollinator population is declining, therefore, it is crucial we protect the species. Specifically, they are excellent buzz pollinators, which is the process of dislodging pollen from the flower by the vibrations of their flight muscles. Do Carpenter Bees Pollinate?īumble bees are important pollinators and are one of the few bee species who can pollinate. If you see large black bumble bees in your yard, there are some easy tell-tale signs for distinguishing between the two. Both are approximately the same size and can be found in some of the same places, including your garden. 113 pp.Carpenter bees and bumble bees are often confused for one another.

Unlike honey bees, bumble bees are quite willing to forage in the still and humid greenhouse air and do not become disoriented in greenhouse conditions. So far, the greatest commercial success with bumble bee pollination has been in greenhouse tomatoes and sweet peppers. This includes tree fruits that bloom in early spring when it is still too cold for honey bees, and crops that require "buzz” pollination (see box). Due to wise regulations against importation of bumble bees from outside their native range, other species are not available.Ī Bombus impatiens colony (photo by Stephen Marshall)Ĭommercial bumble bee providers have manipulated the bumble bee colony life cycle using indoor rearing and husbandry to make mature colonies continuously available to customers throughout the entire greenhouse growing season.īumble bees have either been used successfully or show promise for commercial pollination in several outdoor crops. In the spring, the process begins again.Ī commercial bumble bee industry (using the common eastern bumble bee- Bombus impatiens) is now fully established in Ontario, especially for the pollination of greenhouse crops. The founding queen dies in the fall, and only the young, newly mated queens hibernate over the winter. ![]() At this point, the mated queens disperse and social structure of the original colony begins to break down. When the colony reaches sufficient size, the next generation of reproductive queens and males is produced and mating occurs. Workers take over foraging, cell-building, and tending the young. ![]() The queen then remains in the nest and focuses on egg-laying. In the wild, the mated queen emerges in the spring, finds a suitable nesting site, and raises the first brood of workers by herself. Nectar is only stored temporarily, because only mated queens overwinter. They work under cooler and damper conditions than honey bees.īumble bees do not produce significant quantities of honey. Bumble bee colonies are much smaller than those of honey bees, but the bees are strong and robust. ![]()
