Pest Library » Spiny-backed Orb Weaver Spider

Size:

The body is ½-inch or less in length.

Color:

A brightly colored spider that has a hard, white abdomen with red markings and black spines protruding from the edges.

Behavior:

The spiny-backed orb weaver spins flat, orb-shaped webs in shrubs, trees and in the corners of windows, soffits and similar outdoor areas of buildings. These spiders capture flying, and sometimes crawling, insects found around a home. They are not dangerous and would easily be overlooked if not for their unique coloration. They do not invade indoors unless carried inside while living in a potted plant.
