Are you wondering what spider you found in your yard or home? Are you curious about the spider you saw when walking in nature with your family?

While we cannot list all the spider species, we have put a list together of the most common spiders in Wisconsin, from the most commonly encountered species to some of the least encountered spiders.

7. American Nursery Web Spider

American nursery web spiders

Scientific name: Pisaurina mira

Common name: American nursery web spiders.

The American nursery spider is an ambush predator and does not rely on a web to capture prey.

They get their name from the way the female takes great care of her egg sac. She will gently carry the sac with her fangs, creating a web in shrubs and high weeds, usually suspending it inside a leaf, making it less visible. She then covers the sac in layers of silk, guarding it until the eggs hatch.

The spiderlings stay in the sac for approximately a week before heading out on their own.
