Its been along time, but I "bee lined" and found a bumblebee nest once. Did a little research before I dug them up. If I remember right, the queen is the sole survivor over winter. The balance of the colony perishes, and she starts over in the spring. They store honey in leathery wax pouches. Amazing how little they had stored when I dug them out. One thing to keep in mind.. they don't have a barbed stinger like honeybees. I think it was the same bee that stung me eight times as it angrily walked up my arm. I went back home and put on a couple more layers. It didn't help much. The small colony of maybe 2 dozen critters was mad as hell, which seems completely out of character for the big oafs. Anyway, with so little booty, and large welts all over me, I resolved to leave them alone from that time forward.
