Here are a few ways by which you can identify a nursery web spider based on its physical traits, behaviors, and habits.
1. Body lengths: The body of a nursery web spider can be as long as one-quarter of an inch to one inch, while its legs can be spread out to about three inches.
2. The body color: Nursery web spiders are usually tan, beige, buff, or gray in color. They can also have a sort of dark brown stripes on their bodies.
3. The eyes: Nursery web spiders usually have eight eyes, and they seem to be on two rows horizontally.
4. The shape of its body: A nursery web spider is usually with a slender body. The abdomen is usually wide around the middle and tapers around the rear part.
5. Watch for egg sac: Female nursery web spiders usually carry their egg sacs around until they are almost ready to be hatched.
6. The hunting behavior: unlike several other species of spiders that would spread their web in the trap for prey, nursery web spiders don't usually do that. Instead, they hide, wait for prey, and catch them.
