Is this a bumble bee? If so, where do they nest? I'd like to attract more.
According to the book "Befriending Bumblebees" by Elaine Evans, Ian Burns, and Marla Spivak, the bumblebee you have is Bombus bifarius and is a good candidate for rearing among western bumblebees. Bumblebees nest in holes in the ground, and piles of grass or leaves. Ive seen nests in holes in the side of a shed and down in holes in the side of foundations.
The book mentioned above tells how you can raise bumble bees. I bought a copy just because it's very interesting reading It's available at 1-800-876-8636 or at the link below
