The spider detects the prey by vibrations and, when it comes close enough, leaps out of its burrow to make the capture. Some Conothele species do not build a burrow, but construct a silken tube with trapdoor in bark crevices.

The bright leaves of the Venus flytrap (Dionaea muscipula) attract insects in the same way as flowers. Spiders can be the prey of aggressive mimics. The assassin bug Stenolemus bituberus preys on spiders, entering their web and plucking its silk threads until the spider approaches. This vibrational aggressive mimicry matches a general pattern ...
In some cases the spider vibrates the web of other spiders, mimicking the struggle of trapped prey to lure the host closer. Pholcids prey on Tegenaria funnel weaver spiders, and are known to attack and eat redback spiders, huntsman spiders and house spiders. [10] [11] A cellar spider which has captured a house spider, in a domestic setting.
A bolas spider is a member of the orb-weaver spider (family Araneidae) that, instead of spinning a typical orb web, hunts by using one or more sticky "capture blobs" on the end of a silk line, known as a "bolas".
A collective web of Agelena consociata in Uganda.. A social spider is a spider species whose individuals form relatively long-lasting aggregations.Whereas most spiders are solitary and even aggressive toward other members of their own species, some hundreds of species in several families show a tendency to live in groups, often referred to as colonies.
The spider’s behavior was “surprising” but not entirely novel, he added, noting that some species of bolas spiders attracted male moths by producing chemicals that mimic female moth pheromones.
Spiders also have several adaptations that distinguish them from other arachnids. All spiders are capable of producing silk of various types, which many species use to build webs to ensnare prey. Most spiders possess venom, which is injected into prey (or defensively, when the spider feels threatened) through the fangs of the chelicerae. Male ...
Cheiracanthium, commonly called yellow sac spiders, is a genus of araneomorph spiders in the family Cheiracanthiidae, and was first described by Carl Ludwig Koch in 1839. [4] They are usually pale in colour, and have an abdomen that can range from yellow to beige.
