As night closes in across Kentucky a small chubby spider makes a silk line between two plants. She then moves along her "trapeze wire" and waits. After a while a moth approaches within range, and the spider unleashes a swinging sticky ball, ensnaring the moth and pulling him in to be eaten. The attacker is a bolas spider, and she hunts by releasing an odour that precisely matches the chemical composition of female moth mating pheromones. The male moth is lured in, but instead of getting a mate, he gets eaten.
