Facts About Orange Spiders
Orange spiders—like all spiders—belong to the arthropod class Arachnida. With some types of orange spiders, both the male and female have distinct orange coloring or patterns. With other spider species, it’s just the male or female classified as an orange spider.
How to Identify Orange Spiders
Orange spiders have identifiable orange coloring or patterns on their bodies or legs. All orange spiders are identified by having four pairs of legs, a body with two segments—cephalothorax and abdomen—and eight eyes. Orange spider identification is also possible by looking at the abdomen’s shape, size, and orangey patterns.
Types of Orange Spiders (with Pictures) – Identification Guide
Let’s look at the various types of orange spiders (including black and orange spiders) you are likely to find in your home, garden, or while walking through a park or woodland.
Marbled Orb-Weaver (Araneus marmoreus)
The marbled orb-weaver is the most common type of orange spider. The small marbled orb-weaver spider has an easily identifiable rounded, bulbous brightly-colored orange abdomen with yellowish and black marbling. Other recognizable features of this common spider are its spiny orange, black, and white legs.
Cross Orb-Weaver (Araneus diadematus)
The cross orb-weaver has a pale orange bulbous abdomen with creamy yellowish spots and patches forming a recognizable cross pattern. In addition, the colorful abdomen pattern has mottled markings giving the small spider a patchy appearance. The other identifying feature of this orange spider is its hairy legs.
Woodlouse Spider (Dysdera crocata)
The woodlouse spider is an orange and brown spider with an elongated oval body, long legs, and large mouthparts. The spider’s cephalothorax is typically tawny orange to dark red with a shiny appearance. In contrast, the oval abdomen is a yellowish-brown or dark gray color.
Triangular Spider (Arkys lancearius)

The yellow garden spider is a common species that frequently captures ...
What are yellow spider eggs?
Eggs: Yellow garden spider eggs are spherical and range in color from white to light brown. Eggs are placed in white multilayered tear drop shaped egg sacs, suspended within the spider’s web. These egg sacs are made of a flocculent (wool like) layer of silk used to buffer the eggs and spiderlings from any potential short-term fluctuations of temperature ( Figure 2 ). This flocculent layer is located between the spiderlings and the shell, or outer layer, of the egg sac (Hieber 1985). The yellow garden spider preferentially attaches egg sacs to webbing underneath vegetation or under the coverage of broad-leaved plants (Hieber 1985).
How does Argiope aurantia wrap its prey?
Alternatively, Argiope aurantia may wrap the prey in another technique called rotational swathing, where the prey is wrapped by the spider rotating and attaching silk to the prey simultaneously (Harwood 1974).
What spiders attack Argiope aurantia?
Smaller, younger Argiope aurantia are susceptible to attacks from salticid spiders, commonly known as jumping spiders (Tolbert 1975). Due to their large size, adult Argiope aurantia attacks by salticid spiders are often deterred and salticids may even be preyed upon if caught in the web (Tolbert 1975). Mud daubers will commonly prey on Argiope aurantia. In response to their own predators, Argiope aurantia will create up to two barrier webs within their primary orb web. Barrier webs serve as a physical barrier to some predators by preventing easy access onto the web. Barrier webs are placed on the exterior edges of the orb and more importantly serve to alert the spider of any disturbances in the web (Tolbert 1975).
How do juvenile Argiope aurantia disperse?
Like many spiders, juvenile Argiope aurantia disperse by catching wind currents on silk they release, commonly known as ballooning. Younger spiders typically balloon vertically and begin to balloon horizontally as they mature due to their increased size. Adults are too large to balloon. Figure 3.

The highest densities of Argiope aurantia occur at edge habitats, or where two different habitats meet (Enders 1973). The yellow garden spider frequently is observed in areas disturbed by human development, such as roadsides, farms, and gardens (Enders 1973).
What does it mean when a spider is at rest?
Spiders seen at rest on the hub or center of the web are feeling for vibrations from intruders or prey (Harwood 1974).
