The vibrations from this would-be predator get transmitted to the hub of the web along the silken threads, thus helping the jumper to escape. While suspended on its web, the Anarrhotus sp. may be alerted of a potentially dangerous predator, similar to an orb-weaver. The similarities between the orb web made by the salticid jumper and that of an araneid spider could reflect how these two families use the same approach to solve a common problem-escaping from hungry nocturnal predators. There are few ways in which a spider can efficiently build a web of this kind. The construction of the hub and associated radii resembles the early stages of an orb-web that an araneid spider would make”, he explains, detailing the looks of the web. Like the spokes of a wheel, it is made up of a series of silken threads that meet at the centre of the web or the hub. “Each orb-web is usually oriented vertically on a plant. “This jumping spider exhibits similar behaviour to that of an orb-weaver,” says Dr Abhijith from Mysuru, who is the lead researcher of the study. ![]() jumping spiders, spotted in southwest India, used their orb-webs only as a nocturnal retreat, but not to catch prey. The study, published in the journal Peckhamia, found that adults and juvenile Anarrhotus sp. But building orb webs is a characteristic of another family of spiders-the Araneidae. In a recent discovery, researchers from India and the USA have found that Anarrhotus sp.- a jumper from the family Salticidae-weaves an orb-web as its nocturnal home. builds elaborate tubular shelters with multiple entrances. The weaver, ant-mimicking spider Myrmarachne sp. build a thin sheet out of silk under leaves, while others like Hyllus sp. The nocturnal retreats of salticids are as diverse as the spiders themselves. They do however build nocturnal shelters-a silken home used to retreat to at night. An active hunting lifestyle is no easy task, and even a spider needs a little rest! But, unlike most spiders, these don’t build webs to catch their prey. However, these traits, along with their ability to jump vast distances to capture their prey, makes them textbook examples of active hunters. Their cute front eyes, colours, and elaborate patterns can make even an arachnophobe reevaluate their fears. They belong to the family Salticidae and are one of the most abundant species on the planet. A jumping spider is a master hunter, with large eyes and ability to leap vast distances.
