I was talking to my neighbor Rich the other day and he mentioned something in passing about bumble bees that I didn’t know—all of the bumble bees you see in early spring here are queens. Bumble bees live in underground colonies, consisting of a single female queen bee, female worker bees, and male drones. Most of the bees die off in the fall, but queens that have been fertilized but have not yet nested, overwinter and emerge from hibernation in the spring.
In mid- to late-March this year I had started noticing some especially big, round, furry bumble bees rattling around in the back yard. I like knowing now that they are all fat with progeny, and that they are looking for a spot to nest. I read that they sometimes nest in abandoned rodent burrows, so I dug a little hole next to the compost bin to see if any bees will use it. I suspect now that I am seeing the same bee repeatedly. She is a yellow-faced bumble bee, with a black body and a striking yellow head. She is native, and one of the most common kinds of bumble bees in our area, so I hope to spot more like her over the coming months.
