Prey individuals must distinguish between the cues produced by abiotic factors, competitors and predators, and respond appropriately. We determined whether larvae of Semiothisa aemulataria (Geometridae), which defend themselves from invertebrate predators by hanging on a silk thread, can detect predator threats and […]
