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.
Ballooning, sometimes called kiting, is a process by which spiders, and some other small invertebrates, move through the air by releasing one or more gossamer threads to catch the wind, causing them to become airborne at the mercy of air currents and electric fields.

Spiders (order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, [2] and spinnerets that extrude silk. [3] They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms .
Few spiders are harmful to humans, so you shouldn't worry too much about them in your house. However, Terminix warns of one venomous spider that may seek warmth or food in homes — the brown ...
Spiders have a reputation for giving some humans a fright, but a team of scientists has flipped the script to learn why one increasingly visible species seems to have an edge on handling stress.
A spider could do this only a few ways, like using its silk to float and land in a sleeping person's mouth. But Maggie Hardy, biochemist at the University of Queensland, said, "You'd have to be ...
Pisaurina mira, as one of the most common spiders found in eastern United States, is well integrated in human lives. While the venom of P. mira is lethal to its prey, it is not effective against larger targets and is thus very unlikely to be medically significant for humans.
“In general, spiders will bite only if they can’t get away from you, or are protecting their babies and don’t want to leave the babies behind, and/or they are being crushed or otherwise hurt ...
