American nursery web spider

The American nursery web spider is a brown, long-legged spider that hides in tall grass and bushes. It does not catch food in a web. Instead, it sits very still and grabs insects that come close. The mother is a great carer: she builds a special leafy nursery for her babies.

Fun fact: spiders are not insects. Insects have six legs, spiders have eight. Everyone calls them bugs anyway!
Lives in
Eastern North America, from Canada to Florida and Texas, in tall grass and bushes
