Dry Ice Factory

Yeah, I get the feeling that bumblebees may be very local indeed, because my ceanothus hedge gets just smothered in bees at the same time that ceanothus plants within walking distance of my house don't seem to attract many bees at all. It probably depends on whether the bees have a place to build nests, and I'm beginning to wonder if the little park up the street is where the local ones live. Many species like dead trees or wood fences for their nests.
