The Orb Weaver is a spider commonly found outside homes, in hedges, tall grasses, and trees.

They are a helpful predator who feeds off the pest bugs we don’t like, such as mosquitoes, beetles and other bothersome flying insects. They build elaborate, circular webs and are most often seen in late summer and early fall. They are neither poisonous nor venomous.

5 Incredible Orb Weaver Facts!

  • There are over 3000 species of Orb Weavers worldwide.
  • Females are significantly larger than the males.
  • Several species cannibalize the males after mating.
  • They are docile and non-aggressive, and bites are very rare.
  • They get their name because orb means round and their webs are large and circular, in most cases, though they make adaptations to their circular webs as they mature.

Orb Weaver Species, Types, and Scientific Name

More than 3000 species of Orb Weaver exist all across the world, spread across nearly 200 genera. The common scientific name for the orb weaver is Araneidae.

Appearance: How To Identify Orb Weaver

Since there are so many species with so many body adaptations and variations in appearance, it would be impossible to detail them all here. Some are brightly colored or even golden and have adaptations like spiny bodies. Others have smooth bodies that are not spiny at all. The males tend to be drab and brown. The females tend to be quite large for non-venomous spiders, and their heads are much smaller than their bellies, but one species may look nothing like another, aside from their large round web.

However, identification of the most common female garden spider or Orb Weaver in the United States is very easy. They create large, intricate webs, often creating a zigzag pattern behind which they hide during the daylight hours. She is primarily yellow or golden, white and black with a stripe and dotted pattern on the front of her abdomen and an almost zebra-like pattern on the back with a yellow box in the middle. The front of the head is grayish-white with a pattern resembling a skull and a yellow stripe down the middle of the head on the backside.

Her abdomen is much larger than her head. Her body is about one inch to an inch and a half long. With her abdomen in the air, she resembles a skull wearing a Pope hat. Her leg span is typically between two to three inches across and makes an almost X shape when in repose. Her abdomen is large, and the top portion is somewhat flat rather than rounded, while the bottom is significantly tapered with a rounded end.

The male Orb Weaver looks much different than the female. He will typically be just under half an inch long in the body, with legs that only extend about half an inch across and much closer to his body. He is usually a drab brown or gray with a stubbier, pointier abdomen, though it will still be flat across the middle. His web will be similarly intricate, but generally much smaller and it will lack the zigzag of the female web. They like to build their webs in eaves and across the top of doorways.

Habitat: Where to Find Orb Weaver

When an Orb Weaver builds a web on a home property, they typically like to stretch their webs in between two things, such as between hedges, from walls to hedges, or between two sides of a corner. In their natural habitat, they will form webs between tree branches or tall blades of grass. They prefer to be above the ground, often making webs around four feet in the air, but sometimes they will make webs within a foot or two of the ground, depending on where the prey is.

Diet: What Do Orb Weaver Eat?

Orb Weavers are very beneficial spiders, as they eat a lot of the insects that we consider pests, such as mosquitoes, gnats, and flies. They also like beetles, and some species will eat hummingbirds if one becomes trapped in the nest.

Prevention: How to Get Rid of Orb Weaver

It is really unnecessary to get rid of Orb Weavers or engage in prevention, as they do not bite humans except in rare cases when cornered and they eat many bothersome insects. However, if you suffer from arachnophobia or they build a web across a walkway, the easiest prevention method to dissuade them from making their webs near your house is simply to use a long stick to remove the anchor strands of their webs. This should be done gently, so as not to agitate the spider overmuch. Breaking the web this way will let them know this is not a safe place to build their home and discourage them from building there again. They will typically drop off the web or just run away.
