Bolas: Bolas spiders are unusual orb-weaver spiders that do not spin the webs. Instead, they hunt by using a sticky 'capture blob' of silk on the end of a line, known as a ' bolas '. By swinging the bolas at flying male moths or moth flies nearby, the spider may snag its prey rather like a fisherman snagging a fish on a hook.
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", [ 1 ] hence the English name of the group.

While female bolas spiders hang from a horizontal thread waiting to swing her bolas or sticky orb towards her nearby prey (typically moths), the males do not use a bolas but implement hunting tactics reminiscent of early-instar spiders.
