Gregarious locusts wear contrasting black-brown ‘clothes’ to warn predators

The study reveals the ability of organisms to achieve distinct body color patterns through precise control of pigment deposition. Gregarious locusts use their black-brown warning coloration to enhance aposematism by stimulating both visual and olfactory senses, facilitating recognition of conspecifics and maintaining large swarms.
