Outdoor spiders are hard at work, devouring home and garden pests such as ants, flies, mosquitoes, aphids, and thrips. It’s estimated they kill 400 to 800 million metric tons of prey worldwide ...
Ballooning is a behavior in which spiders and some other invertebrates use airborne dispersal to move between locations. [ 4 ] [ 5 ] A spider (usually limited to individuals of a small species), or spiderling after hatching, [ 6 ] will climb as high as it can, stand on raised legs with its abdomen pointed upward ("tiptoeing"), [ 7 ] and then ...
Electron micrograph of housefly pulvilli, the finely hairy pads on their feet that enable them to stick to walls and ceilings. Arthropods, including insects and spiders, make use of smooth adhesive pads as well as hairy pads for climbing and locomotion along non-horizontal surfaces.
In certain groups of spider species, so-called cribellate spiders, the cribellum is a silk spinning organ. Unlike the usual spinnerets of spiders, the cribellum consists of one or more plates covered in thousands of tiny spigots, tiny holes that hardly project from the surface, in contrast to the elongated spigots that project from spinnerets.

Fredericks says late summer and early fall are peak seasons for spiders, and plentiful rain in any region during the summer can cause insect populations to boom, creating more food for spiders.
Spiders that spin webs typically have three claws, the middle one being small; hunting spiders typically have only two claws. Since they do not have antennae, spiders use specialised and sensitive setae on their legs to pick up scent, sounds, vibrations and air currents. [6] Some spiders, such as the Australian crab spider, do not have claws.
