Animals employ various strategies to defend themselves against predators. Our research focuses on the anti-predator defenses of invertebrates, including caterpillars, beetles, wasps, assassin bugs, praying mantises, and snails. We have used predator such as carabid beetles, braconid parasitoids, orb-weaving spiders, praying mantises, toads, and frogs to conduct our investigations.
