Tricolored Bumble Bee

Fascinating facts about the Tricolored Bumble Bee

• A queen bumblebee can be as long as a small paperclip, measuring 17-19 mm, while a worker is barely half that size at 8-13 mm. Yet the queen outweighs her tiny sisters because her abdomen is packed with fat, whereas workers keep their bellies almost empty to make room for a huge honey-stomach.
• A single queen burns through roughly 600 mg of sugar each day to keep her brood warm, a cost that forces her to sip from up to 6,000 flowers daily. Even with that massive appetite, her underground nests never grow beyond about 200 individuals. The staggering daily sugar bill shows how vital abundant flower fields are.
• The orange-belted bumblebee's life is a one-season sprint that starts when the queen awakens from hibernation in late April, emerging from a few inches of soil or leaf litter. Workers then take to the air from May through October, gathering food until the whole colony, except the hibernating queens, dies in mid-autumn.
• Mating can last anywhere from ten to eighty minutes, but the crucial sperm transfer happens in the first two minutes. Afterward the male seals the queen's reproductive tract with a sticky plug that stays in place for about three days, blocking rivals and giving the first male a better chance to father the next brood. Queens split their strategies: roughly half switch early to produce mostly drones, while the other half wait and lay mostly new queens, creating a near-even sex ratio that deviates from the usual three-to-one Hymenoptera pattern.
• A foraging orange-belted bee can travel up to 6 km from its nest, and when flowers are scarce it may push that distance to 20 km. Yet it rarely fills its nectar crop to the brim because each gram of nectar adds extra weight, forcing the bee to burn more energy than the sugar it carries returns.
