Supplement to Harvesting Ants and Trap-Door Spiders

The work collects field observations and experiments on seed-harvesting ants and the construction and variety of trap-door spider nests, combining behavioral notes, anatomical and species descriptions, and detailed plates and diagrams. It details granary structure and experiments probing how ants prevent stored seeds from germinating, reporting confinement trials and vapour tests that point toward active ant intervention rather than purely physical nest conditions. The supplement classifies nest types, illustrates spider morphology and nest architecture, and interleaves natural-history description with experimental methods and taxonomic notes to document ecology and species-level features.
