Description

The Spiny-backed Orb Weaver Spider is a very small, brightly colored garden spider that spins an orb shaped web. This colorful spider has a body of yellow, white or orange, with red spines that point outward. Males are about 1/8” long while females are larger at 3/8″. In some regions it is also called a “crab spider”.

The female Spiny-backed Orb Weaver Spider spins a new web each night in a plant or on a building, often where flying and crawling insects are attracted to a light. A male will wait nearby. They are not aggressive toward humans and only deliver a harmless bite if held.

The Spiny-backed Orb Weaver Spider has a short lifespan. The male dies soon after mating and the female dies soon after producing her egg sac.

Control Advice

If found inside, relocate the spider outdoors if possible. Limit vegetation near the house to reduce spider activity close to the home. Use yellow ‘bug’ lights for overnight lighting.

Active Seasons

The Spiny-backed Orb Weaver Spider is most active in spring, summer and fall.
