The orb weaver spider family includes over 2,800 species spanning across the globe. Among the many species of spiders, one that stands out for its intricate web-building abilities is the orb-weaver spider. From their mesmerizing web designs to their unique hunting techniques, we will delve into the fascinating aspects of these eight-legged creatures.

The orb weaver spider family is the third largest in the world. Garden Orb Weaver Spider. Commonly seen in the United States, garden orb weaver spiders are typically between 1.5-3 centimeters in body length. They are an outdoor spider and most types are never found inside the home.

Chris Conlan said rain creates more vegetation and more insects and spiders. This means orb weaver spiders have more tiny bugs to eat and they’re thriving.

Using a stress-testing machine, the researchers revealed the golden orb-weaving spiders silk is up to a hundred times tougher than synthetic products used for medical surgeries. The spider Nephila inaurata can spin a web exceeding 3 feet in diameter. About the size of a CD, a newly described spider is the largest web-spinner.

They have chemoreceptors in their tarsi used in chemical detection and olfaction. An airborne pheromone is released by females which attracts and helps communicate with male mates. The garden orb weaver is 0.78-1.57 in for the female and 0.59-0.78 in for the male.

Once snuggled, spiders enter diapause. The body-length of a female Nephila komaci is 1.5 inches with legs spanning 4-5 inches. Unlike other spiders, they build nests to last – sometimes years. Orb weaver spiders are not poisonous to dogs. Shamrock spiders prefer to remain in their webs.

Many orb weavers brightly colored, hairy legs and large overlapping abdomens. Nocturnal orb weavers brown or gray. Orb weavers rarely bite; only threatened. Comparable to a bee sting unless hyper allergic.

Largest spider web, 82 feet wide, was made by Darwin’s bark spider with strongest silk. Orb builders make flat webs with sticky spirals. Engineering feat begins floating line in wind. Secures then drops line from center making “Y” shape. More nonsticky silk before final sticky spiral.

Housing spiny orb weaver often mesh preventing wandering while allowing stunning web. Cage of 24” x 12” x 12” good for spiderlings and males.

Family over 2800 species 160 genera worldwide. Third largest after jumping spiders and sheet weavers. Oldest orb weaver, Mesozygiella dunlopi, dates Lower Cretaceous amber.
