The ceanothus is abuzz all day, and now the California bees Bombus californicus are out after their winter rest, as well.

I wonder if these are nesting underground or in the tufts of native grasses that are growing nearby in our native patch.

These bumble bees are very quick, darting around with sudden movements.
