Orange garden spiders are known for their bright yellow and orange coloration. These spiders, known as orb weavers, build webs that are spiral-like in appearance with fibers that radiate out to the sides. Most people envision this type of web when thinking of spider webs. These spiders are fairly large, measuring about an inch in body length.
They tend to attach their webs to bushes, trees, fences, or tall vegetation, and their webs can be quite large. The silk used in the web is sticky in order to ensnare prey, but the spider does not get caught in it due to a substance on its legs that keeps it from sticking. Because garden spiders have poor eyesight, they rely on the vibrations of prey caught in the web to alert them to its presence.
The orange garden spider creates a characteristic zig-zag pattern in its web, known as the stabilimentum. Because of this, garden spiders are sometimes referred to as “writing spiders.” The stabilimentum may have several functions, such as helping to alert the spider to ensnared prey; deterring larger animals, such as birds, from disturbing the nest; or, as the name may suggest, helping to stabilize the web. These spiders tend to rebuild their webs each day.
This spider will hang down from the web as it awaits prey. Like most spiders, the orange garden spider injects its prey with venom to paralyze it and also secrets a digestive enzyme liquefy the insect before consuming it. The spider will also wrap the prey in silk.
The bite of an orange garden spider is not harmful to people, unless an individual has some type of allergic reaction, which is quite uncommon. In fact, these spiders are considered beneficial to humans because they help to control the population of other types of pests.
