Key facts and history

The English name "orb-weaver" comes from the word "orb" meaning "circular"[2] Orb-weaver webs are built in a stereotypical fashion, with a nonsticky silk framework followed by a sticky spiral.[1] Sexual cannibalism is common in the family, with male Argiope bruennichi cannibalized in up to 80% of cases.[3][4] An insect that becomes entangled in the sticky capture threads receives a rapid bite that immobilizes it, after which the spider envelops it in silk.[5]

When the captured prey is venomous, the spider may wrap it in silk before biting.[5] A crisscross silk structure called a stabilimentum is placed through the web's center by certain orb-weavers, especially those in the genus Argiope.[6]

What the cited sources add

Deinopoidea have a cribellum and calamistrum, structures absent in Araneoidea.[7][8]
