Bolas Spiders

Bolas Spiders are unusual orb-weaver spiders that do not spin the typical web. 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. Because of this, they are also called angling or fishing spider (although the remotely related genus Dolomedes is also called fishing spider). The prey is lured to the spider by the production of up to three pheromone-analogues.
