The beekeeper opens the upper part of the hive and examines the super. Instead of serried rows of bees sealing up every gap in the combs and keeping the brood warm, he sees the skillful complex structures of the combs, but no longer in their former state of purity. All is neglected and foul. Black robber bees are swiftly and stealthily prowling about the combs, and the short home bees, shriveled and listless as if they were old, creep slowly about without trying to hinder the robbers, having lost all motive and all sense of life. Drones, bumblebees, wasps, and butterflies knock awkwardly against the walls of the hive in their flight. Here and there among the cells containing dead brood and honey an angry buzzing can sometimes be heard. Here and there a couple of bees, by force of habit and custom cleaning out the brood cells, with efforts beyond their strength laboriously drag away a dead bee or bumblebee without knowing why they do it. In another corner two old bees are languidly fighting, or cleaning themselves, or feeding one another, without themselves knowing whether they do it with friendly or hostile intent.
