Bumble bees are found almost world wide in distribution. Unlike most social insects, they are most numerous in temperate climates. Occasionally, they are even found in Arctic zones. All are nest builders and the colony consists of queens, drones, and workers. Bumble bee colonies generally contain a few hundred individuals, although the population of a thriving colony may reach between 1,000 and 2,000 bees. These bees are the best pollinators in the world because of the size and the rapid movement of their wings. They are sought after by tomato farmers who believe the pollination effectiveness of one Bumble bee is worth several hundred honey bees. Bumble bees are easily recognized by their size (about an inch) and color (all have black and yellow, most species have bands).

Life Cycle:

Fertilized Bumble bee queens must hibernate by digging a small chamber in the soil. In spring, they reappear and establish a nest. The queen then builds a "honey pot" and fills it with nectar, then builds a cell, usually from a mixture of wax and pollen, for her eggs. The eggs of the first brood vary in number from 1 per cell to as many as 10-12. While the colony is in the early stages of development, some of the queen's eggs are never laid, but are reabsorbed. The larvae hatch in 3-5 days. About 3 weeks are required for larval and pupal development stages. If larvae receive ample food, they become queens, but if partially starved, they become workers.
