Well, yeah, "bee butts". If I see those, then I know my garden is attracting lots of bumble bees. I have two varieties attending to my garden. One is plump and fuzzy, mostly black with a bit of bright yellow. I started with one and now he visits with one or two other bees. The other variety is a more slender bee with even black and subdued yellow stripes. A "yellow jacket"?
Apparently they prefer different flower nectar.
I am greatly amused to see the Full Immersion approach of the bumble bees when it comes to the torena (see last photo).
Additionally, you may insert comments throughout the blog in the spaces provided for "comments". There is also a "Question and Answere" portion to this blog, located at the bottom of the blog. This is open to all. Accordingly, if I cannot answer your question, perhaps another reader will be able to do so.
