It is true the bumblebee may dwell among almost any flowers, but
he has decided preferences for such showy ones as have adapted
themselves to please his love of certain colors (not yellow), or
have secreted nectar so deeply hidden from the mob that his long
tongue may find plenty preserved when he calls. Occasional
visitors alighting on the agrimony for pollen may distribute
some, but the little blossoms chiefly fertilize themselves. When
crushed they give forth a faint, pleasant odor. Pretty, nodding
seed urns, encircled with a rim of hooks, grapple the clothing of
man or beast passing their way, in the hope of dropping off in a
suitable place to found another colony.
