Week 2: Silk and Web

Spider of the Week: The Orb Weaver Spider (Family Araneidae)


The orb weaver...
Orb weaver spiders are our Spider of the Week because they create the webs that we associate with "typical" spider webs. We highlight these beautiful webs as a great example of spider silk and its many uses, starting here with a spider's most common use -- webs.


The orb weaving spiders craft the familiar "garden variety" structures that most people picture when they think of spider webs. With its legs poised on silken strands, the orb-weaver waits to feel the vibrations travelling down the threads from its struggling prey. The orb weaver then pounces onto the prey and subdues it with a venomous bite. For the final step, the orb weaver spider wraps its paralyzed prey in constricting silk.
