Nursery web spiders

Pisaura mirabilis

European nursery web spider

Before mating, the male offers the female an insect wrapped in silk, and will sometimes feign death to avoid being eaten while presenting this nuptial gift.

This slender, long legged spider is grey to reddish brown with a pale stripe running down the middle of the back, and is often mistaken for a wolf spider at first glance.

The female carries her egg sac gripped in her fangs rather than attached to her spinnerets, and just before the spiderlings hatch she spins a silk nursery tent around the sac in low vegetation and guards it closely until they disperse.
