Cockroach Anatomy and Behavior - Classic Scientific Illustration #1487340 (License: Personal Use)

This black-and-white engraved illustration shows three cockroaches in dynamic poses, with labels 'a' and 'b' highlighting specific individuals for comparative study. Fine cross-hatching renders exoskeletal texture, antennae length, leg segmentation, and wing structure-typical of 19th-century entomological plates. The scene suggests aggregation behavior near a substrate edge, possibly indicating pheromone-mediated grouping or shelter-seeking.
