Harvesting Ants and Trap-Door Spiders / Notes and Observations on Their Habits and Dwellings

A naturalist's study of seed‑harvesting ants and burrowing trap‑door spiders that blends detailed field observation with anatomical and architectural illustration. The author documents how harvesting ants gather, process, and store seeds in subterranean granaries, sort and eject refuse to form surface middens, and influence local seedling growth, while describing nest layouts and worker specialization. The account of trap‑door spiders focuses on burrow construction, silk lining and hinged doors, and ambush predation techniques. Numerous plates and explanatory notes accompany the observational descriptions, emphasizing behavior, nest engineering, and life‑history details.
