Many species of nursery web spiders are able to walk on water and dive after prey. They feed on insects, worms, small fish and tadpoles. This species, like many others, is known to engage in sexual cannibalism, where the male is eaten after mating.
How do nursery web spiders reproduce?
The first step in the reproduction of nursery web spiders is courtship. Male spiders usually court a female by offering her a “nuptial gift.” The male captures a fly or some other insect and spins a cocoon around it, then offers it to the female. When a nuptual gift is accepted, the male completes copulation.
