The Mason-Bees

A sequence of close field studies that trace the nesting habits, provisioning, and life-cycles of mason bees and related wild bees, combining patient observation with controlled experiments on navigation, nest exchange, and parasite interactions. Complementary essays consider red ants, domestic animals, and parasitoid wasps to illuminate orientation, instinct, and host–parasite relationships; reflections on insect psychology and the theory of parasitism synthesize empirical findings. Vivid anecdotes and experimental detail make the natural-history investigations both descriptive and analytical, emphasizing how behavior, environmental cues, and parasitic strategies shape the bees' fortunes.
