There are few insects that are as kindly thought of than bumble bees. They are often portrayed in children’s stories and poems as friendly, happy characters that seldom cause trouble. Their name “bumble” derives from Latin roots meaning “to buzz or drone” which clearly describes the sounds heard from bumblebees. In a more modern sense, “bumble” also means to move awkwardly or ineptly which characterizes the manner in which bumblebees seem to fly around from flower to flower. They appear more relaxed in their efforts than their hard-working honey bee cousins.
Bumblebees (Bombus) are easily recognized by their quite large, plumplooking size and their distinctive black and yellow banding, which sometimes includes orange markings as well. Their roundish bodies are very well covered with hairs that are quite soft and fuzzy feeling. They are rarely territorial or aggressive like wasps and generally don’t sting people but will if they feel threatened enough.
Bumblebees are social insects in the insect order Hymenoptera which includes other highly social insects such as wasps and ants. Just like honey bees, bumble bees live in colonies with a queen, workers and drones, but their colonies are much smaller in number than those of the honey bees. Bumblebee colonies, or nests, are typically found in the ground in the abandoned nests of other creatures such as mice and burrowing birds. In Canada, bumblebee nests are newly created on an annual basis. Only fertilized queens will overwinter and in the spring these queens will each find a suitable nesting site to build their colonies.
Bumblebee workers forage for nectar and pollen to feed themselves and the young in the colony. They have long, hairy tongues to gather nectar from flowers and are especially good for helping to pollinate plants with deep flowers such as some of the commercially grown clovers.
The hind leg of the female bumblebee is modified to have an area with a pollen basket. This is a bare area that is surrounded by hairs and it is in this spot that bumblebees transport the pollen they collect from the many, many flowers they visit every day. They can carry relatively large amounts of pollen which can be very easily seen on almost any bumblebee a person encounters.
