Feather Horned Beetle with Long Bushy 'Eyebrows'(Rhipicera femorata): Males use their fantastic (hah!) antennae to locate a female feather-horned beetle that’s emitting pheromones which indicate she is ready for mating. Photo by ron_and_beth.
The saddleback caterpillar has fleshy horns that sit at each end of the body and are covered in hairs that secrete venom. Brushing up against them causes pain as strong as that from a bee sting, swelling, nausea and a rash.
