Where do bumble bees go in winter?
Bumblebees: Colonies die out at the end of the summer. Only young fertile females (queens) survive the winter, in hibernation in nooks and crannies under the ground, in a deep sleep.
Do bumble bees sleep on flowers at night?
They also sleep in flowers that close up for the night, like CA poppy (Eschscholzia californica), which probably keeps them safe from predators. As soon as the day starts to warm up the bees will begin stirring and again begin their search for females to mate with.
