Orb weaver

From WikiMD's Food, Medicine & Wellness Encyclopedia

Orb-weaver spiders or orb weavers (Araneidae) are a family of spiders that are known for their intricate web-building abilities. They are one of the three largest spider families, with over 3,100 species in 169 genera worldwide.

Description[edit | edit source]

Orb weavers are known for their bright and often colorful bodies. They vary in size, with some species measuring less than a centimeter, while others can reach sizes of up to 28 millimeters. The body shapes of orb weavers can also vary widely, from the typical spider shape of the garden spider to the elongated abdomen of the golden silk orb-weaver.

Behavior[edit | edit source]

Orb weavers are most famous for their spider webs, which they construct in a circular "orb" shape. These webs are used to capture prey, which typically consists of flying insects. Some species of orb weavers will rebuild their webs every day, typically at dawn or dusk.

Habitat[edit | edit source]

Orb weavers can be found in a variety of habitats, including gardens, fields, forests, and even human structures. They are widespread and can be found on every continent except Antarctica.

Reproduction[edit | edit source]

The reproduction process of orb weavers involves the male depositing sperm into the female's epigyne, a reproductive organ unique to spiders. After mating, the female will lay her eggs and wrap them in silk for protection.

Human interaction[edit | edit source]

While orb weavers are venomous, they are not considered dangerous to humans. Their venom is used primarily for subduing their prey. In fact, many people appreciate orb weavers for their pest control abilities, as they help to reduce populations of flying insects.
