What is an Orb Weaver Spider?

An orb weaver is a spider belonging to the family Araneidae, noted for spinning large, circular webs. The term “orb” refers to the shape of the web itself, while “weaver” refers to the spider’s skill in crafting these intricate traps. With hundreds of types of orb spider species worldwide, they vary greatly in size, color, and pattern. Some have bright hues like yellow or red, while others blend into their surroundings with earthy tones of brown or green.

How to Identify an Orb Weaver Spider

Orb weaver identification begins with noting the shape of the web: If you see a large, symmetrical web shaped like a wheel, you’re likely dealing with an orb weaver. These spiders typically rest upside down in the center of their web or in a hidden spot nearby. Their bodies are often more rounded compared to other spider families. Some types of orb weaver spider have pronounced abdomens with distinctive patterns, while others may be more subdued.

Look closely at the spider’s legs—many orb weavers have slightly longer legs at the front, though this can vary by species. Their overall size can range from a few millimeters to over a centimeter in length, depending on the orb weaver species. Males are usually smaller than females, and the female’s abdomen is often bigger and more patterned.

What Do Orb Weaver Spiders Eat?

Orb weavers feed on flying insects like moths, flies, mosquitoes, and small beetles. Their webs serve as highly effective traps, using sticky silk threads to snare unsuspecting prey. Once an insect becomes entangled, the weaver spider rushes out to wrap it in silk, inject venom to subdue it, and then carry the meal away to a safe spot on the web. Their diet helps control insect populations in gardens and other outdoor areas.

Are There Different Types of Orb Weaver Spiders?

The Araneidae family includes many types of orb weavers adapted to various climates and conditions. Some species prefer the sheltered corners of forests, while others thrive in open fields or near homes. Certain orb weavers have unique features like spiny abdomens or elongated bodies that help them blend into foliage or even mimic the look of twigs.

Are Orb Weaver Spiders Venomous?

All spiders, including orb weavers, have venom glands. However, orb weaver venom is generally mild and not considered dangerous to humans. Bites are rare, and most people experience little more than a mild irritation like a mosquito bite. Orb weavers would rather flee than fight, and their slow, deliberate hunting style is geared toward small insects.

Can Orb Weaver Spiders Harm Pets and People?

No, orb weavers pose virtually no threat to people or pets. If a curious pet sniffs an orb weaver, the spider is more likely to drop from the web and scurry away than to bite.

How to Get Rid of Dangerous Spiders

While orb weavers are generally harmless and even beneficial, not all spiders deserve a free pass. Some species, like black widows and brown recluses, pose genuine risks to humans and pets. If you suspect these dangerous arachnids or other threatening pests in and around your home, professional pest control can help eliminate the problem and restore safety and peace of mind to your property.
