Description of the spotted orb weaver

The abdomen, which is usually a shade of brown or reddish brown, has a slight pattern but nothing that stands out, and is usually covered with thick hairs. The legs will have brown or red-brown coloring closer to the body and have black and white / tan bands on the half furthest away from the cephalothorax.

The body of the female adult will grow to ¾ of an inch (19mm). If you include the legs, they can reach around 1 ½ inches (38mm).

Web

As any orb weaver, the spotted orb weaver spins webs to catch small insects. The web is orb-shaped and is rebuild every day.

Bite

The spotted orb weaver is not an aggressive spider. However, in some situations, it occurs that it bites a human or a pet. The symptoms are usually comparable with a bee sting and will not have any long term negative effects.
