The most common orange spiders are the marbled orb-weaver with its bulbous orange abdomen and orange and black patterns. There are various different species and sub-species of spider with orange back.

This is because they can exhibit a wide range of colors, including shades of yellow, red, brown, and black. In this article, I will tell you all about spiders with orange backs and lay out different types of similar spiders!

Are there other types of spiders that have orange backs?

Interestingly enough, there are other species of orange arachnids in the world. For example, the woodlouse spider is a common household spider that is typically found in dark and moist places such as basements or crawlspaces.

The cross orb-weaver spider is an unusual-looking spider that spins webs with spokes radiating out from the center like a cross. And finally, triangular spiders get their name because of the three points on their abdomen.

In addition, there are many different species of spiders that have orange and black bodies. For example, the jumping spider is a small arachnid that can be found all over the world.

What should you know about spiders with orange backs?

Spiders with orange backs can be found all over the world. They belong to the arthropod class Arachnida, which includes spiders, scorpions, and ticks. These spiders are known for their eight legs and two body segments.

There are different types of spiders with orange backs, and each comes with its own set of identifying characteristics. For example, some spiders have an orange coloring or pattern that is very distinct.

Others may just be classified as male or female spiders due to their coloration. In any case, it is important to be able to identify an orange spider when you see one!

In addition to their color, one of the most distinctive features of orange spiders is their eyes. Most spiders have eight eyes, but orange spiders usually have two larger eyes in the front and six smaller ones on the sides. This allows them to see better in dim light.

Interestingly, there are dozens of spider species that sport this coloration. And while they may look strikingly similar to some other spiders, they can generally be identified by their characteristic black head and thorax. I’ll tell you more about identifying orange spiders in the next section.

These spiders are usually tiny jumping spiders, which means they aren’t as large as some of the other common spiders you might see around your home.

Almost all species of orange spiders spin a silky web. However, not all of them use their webs to catch prey as red widow spiders do. Instead, they use their webs for other purposes such as protecting eggs, hiding from view, or transporting objects.

How can you identify orange spiders and distinguish between other insects and them?

Although it can be difficult to identify an orange spider, there are a few key features that will help.

All orange spiders have four pairs of legs, i.e., eight legs in total. Spiders, whether orange or black, have bodies with two distinct segments — the cephalothorax and the abdomen—and eight eyes.

The shape of the abdomen can give clues as to its identity. The size is a good indicator that makes it easy for you to spot spiders. And finally, the orange-colored patterns on its back will help confirm whether it’s an orange spider or not.

Don’t expect spiders to have wings and fly about your house. That would make poisonous spiders extremely formidable insects to deal with. However, spiders have other predatorial characteristics.

Not only can these insects jump and creep to where they want to go, but they can also stun or kill their prey with venom and elaborate webs that are meant to trap their prey.

Most other species of insects have three pairs of legs, and as far as the insects that you will typically find in your house are concerned, many of them will have wings!

Now let’s get to know them in detail

1. Marbled orb-weaver spiders (Araneus marmoreus)

oranged Marbled Orb Weaver Spider.

The marbled orb-weaver spider is the most common type of spider with an orange back. This common spider has easily identifiable rounded, bulbous, brightly-colored abdomens with yellowish and black marbling.

They can be found throughout North America and are often spotted in gardens and yards.

Another distinguishing feature of the orb-weaver is its spiny orange, black, and white legs. Additionally, this spider is relatively small; it measures 0.35″ to 0.79″ (9 – 20 mm).

The marbled orb-weaver spider is so named because of its characteristic markings. Additionally, they build large webs in open areas between trees and shrubs.

The spiders get their name from the orange and black markings on their abdomen, which can resemble a pumpkin. There are many different species of marbled orb-weavers, all of which have similar colors and markings.

The patterns may be a light brown or tan with a black outline contrasting against the bright orange color. Other species have a pale orange, almost yellow abdomen with a large brown patch at the rear. The cephalothorax (head) of all Orb Weaver spiders is typically dark orange.

How to identify male marbled orb weaver spiders?

Male marbled orb weaver spiders are easily identified by their oval orange-yellow abdomen with black or dark brown patterns.

They have dark orange cephalothorax and dark orange legs with black and white bands. The male marbled orb weaver spider measures 0.12″ to 0.23″ (3 – 6 mm).
