Nursery web spider

Know more?

Before mating the male of the Nursery web spider catches a fly, but doesn’t eat it! On the contrary, he wraps the prey with silk and turns it into a gift for the female. The female is distracted while opening and consuming the gift, allowing the male to mate. Sometimes the male even dares to give a fake gift such as an empty fly or a piece of flower. The female carries her egg sac in her fangs (wolfspiders use the spinnerets for that). When the eggs are about to hatch, the female constructs a dome-shaped nursery web. In there, she guards the egg sac and the newly hatched young.
