“We like big bees and we cannot lie.” -Sir Mix a Lot, sort of.
That said, you probably won’t see too many big bees like this bumblebee (most likely Bombus nevadensis) this time of year…or small bees for that matter. So where did they go? If a female bee emerged late in the summer, she might hibernate over the winter in a hole in the ground, in a tree, or in a hollow stem, and lay her eggs early in the spring. Otherwise, most adult bees die when the flowers turn into fruits. However, bees have many stages in their life cycle, so while you might not see adult bees, baby bees are using the winter to grow big and strong!
Most native bees don’t live in colonies. Instead, many bee species are solitary, meaning that each female bee can and does lay her own eggs. When a bee lays eggs, she will usually leave behind “bee bread,” or pollen mixed with saliva and formed into a ball, for the baby bee, or larva, to feast upon once it hatches. Each egg is typically laid in its own chamber and then sealed off from predators. When the larva first hatches, it will spend much of its time munching on the bee bread its mom left behind. As time goes by, larvae grow bigger and stronger, eventually going through several metamorphoses until they transform into adults come spring.
So next time you’re wandering around in the winter, feeling like everything is dead, remember that there’s plenty of life still there, growing and waiting until the time is right to emerge.
