Orb weaver spiders are typically nocturnal, building and repairing their webs at night. At dawn, some orb weavers will tear down their webs and eat them to take in moisture from the dew that collects on them and to prevent larger animals like birds from becoming trapped in them.

Orb weavers rarely bite and only do so when threatened and unable to escape. If bitten by an orb weaver, the bite and injected venom is comparable to that of a bee sting, with no long-term implications unless the bite victim happens to be hyper-allergic to the venom.

Is the orb weaver spider poisonous?
Orb weaver spiders are not poisonous. They may contain mild venom, but it isn't harmful to humans or even large animals.
Where do orb weaver spiders go during the day?
Daytime/Nighttime Activities: Orb weavers are typically nocturnal. During the day, the spider will prefer to either sit motionless in the web or move off the web. If the spider moves off the web (but does not abandon it), she will be nearby in some cover (rolled up leaves, or on a branch) with a trap line nearby.
Why do orb weavers come out at night?
Their web is designed to catch flying insects, and the most common at night are moths and beetles. When prey strikes the web, Garden Orb-weavers move like lightning – they must. If they give a struggling insect time to thrash around in the web, it will usually free itself, so speed is of the essence.
Are orb spiders good to have around?
They're harmless to humans and are, in fact, beneficial garden residents for their constant pest control. This time of year, orb-weavers are busy spinning their large, circular webs—some up to 3-feet in diameter—in spots where pests are readily available: in flower and vegetable gardens, parks, fields, and forests.

What is the lifespan of an orb weaver spider?
one to two yearsIn areas with cold winters, the female orb weaver will lay a large clutch in the fall and wrap it in thick silk. She will die when the first frost arrives, leaving her babies to hatch in the spring. Orb weavers live one to two years, on average.
How do you keep orb weaver spiders away?

Where do orb weavers go in winter?
Many spiders adapt to staying outside throughout the winter, even in the coldest areas. Some species, such as the orbweaver Araneus saevus, spend the winter in egg form and hatch during warmer weather. Others, such as the male hackledmesh weaver (Amaurobius and Callobius sp.), overwinter as immature spiders.

Appearance
The orb weaver spider group is comprised of a large number of species thus making it difficult to distinguish them from other spider groups and from each other. In fact, the Orb-weaver spider family, Araneidae, is one of the most variable in size and appearance of all spider families.
Behavior
Orb weavers are typically nocturnal spiders and many species will build or do repair work on their webs at night. Some orb weaver spiders tear down and even consume much of the web's silk as the morning begins to dawn.
Diet
Small insects such as flies, moths, beetles, wasps and mosquitoes are examples of insects that make up the spider's diet. Some of the larger orb weavers may also trap and eat small frogs and humming birds should they venture into the web. Orb weavers tend to inhabit locations where there is abundant prey and structures that can support their web.
Reproduction
Male orb weavers are much smaller than females and the male's role in to mate with the female. Since the males are small, it is not uncommon for them to become the female's first meal after mating. Female orb weavers produce one or more egg sacs and each sac may contain up to several hundred eggs.
Signs of Infestation
Presence of the web is the most obvious sign of an orb weaver population
Distribution
Orb weavers are found throughout the world, except for the Arctic and Antarctica. In North America, there are approximately 180 species of orb weaver spiders.
What is an orb weaver spider?
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word orb can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.

What is a globule in a bolas spider?
The globule is hung from a silken thread dangled by the spider from its front legs. The pheromone analog attracts male moths of only a few species. These get stuck on the globule and are reeled in to be eaten. Both genera of bolas spiders are highly camouflaged and difficult to locate.
What is an araneid web?
Araneid webs are constructed in a stereotyped fashion. A framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families.
Why do orb weavers have bands?
As orb-weavers age, they tend to have less production of their silk, many adult orb-weavers can then depend on their coloration to attract more of their prey. The band may be a lure for prey, a marker to warn birds away from the web, and a camouflage for the spider when it sits in the web.
Where do araneids mate?
Araneid species either mate at the central hub of the web, where the male slowly traverses the web , trying not to get eaten, and when reaching the hub, mounts the female; or the male constructs a mating thread inside or outside the web to attract the female via vibratory courtship, and if successful, mating occurs on the thread.

What family are Charlotte's orb weaver spiders in?
The BugLady has been amassing shots of big, showy orb weaving spiders (Charlotte’s relatives) in the spider family Araneidae. FYI, in the course of her research, she has seen the name spelled Orb Weavers, Orb-weavers, and Orbweavers. She thinks she’s ID’d them correctly, but “picture-keying” has its limits, and there’s a lot of variability within each of these species. If she were smart, she would be satisfied just to get the genus right. The BugLady invites BugFans to visit bugguide.net, type the names of these spiders into the search box, click on “Images” and be blown away by the different colors and patterns of each. The BugLady also recommends Spiders of the North Woods by Larry Weber. Whoever they are, aren’t these spiders fine! Here, a bit late for Halloween, is something for Arachnophobes.
Who recommends Spiders of the North Woods?
The BugLady also recommends Spiders of the North Woods by Larry Weber. Whoever they are, aren’t these spiders fine! Here, a bit late for Halloween, is something for Arachnophobes.

What is the cross orbweaver?
The Cross Orbweaver ( Araneus diadematus) is an alien spider who, like the Bridge spider of recent BOTW fame, immigrated to our shores from Europe (it’s also called the European garden spider and the Diadem spider). Like the bridge spider, it likes to hang out on buildings, especially on walls with exterior lights.
How long does it take for a spider to make a spiral?
If it catches on something, the spider forms the “spokes” of the wheel with non-sticky web and then uses sticky silk for the spiral. It takes about an hour. Some (but not all) diurnal OWs, especially in the genus Argiope, weave a heavy “zipper” or other pattern called a stabilimentum into part of the web.

The English word orb can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.
Description
Generally, orb-weaving spiders are three-clawed builders of flat webs with sticky spiral capture silk. The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. The spider secures the line and then drops another line from the center, making a "Y". The rest of the scaffolding follows with many radii of nonsticky silk being constructed before …
Taxonomy
The oldest known true orb-weaver is Mesozygiella dunlopi, from the Lower Cretaceous. Several fossils provide direct evidence that the three major orb-weaving families, namely Araneidae, Tetragnathidae and Uloboridae, had evolved by this time, about 140 million years ago. They probably originated during the Jurassic (200 to 140 million years ago). Based on new molecular evi…
