Bombus impatiens

Also known as Common Eastern Bumble Bee, Eastern Bumblebee

Common eastern bumblebees live in highly organized eusocial colonies featuring a single queen and hundreds of sterile female workers. Active from early spring to late autumn, workers employ buzz pollination, vibrating their flight muscles to release tightly held pollen from crops like tomatoes and blueberries. Reproductive gynes and males emerge in late summer, after which mated queens hibernate underground to found new colonies the following spring.
