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.

A male Eresus sandaliatus. Sexual selection in spiders shows how sexual selection explains the evolution of phenotypic traits in spiders.Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species surviving only a few matings and consequently having short life-spans.
The jumping spider Evarcha culicivora uses the scent of blood from mammals and other vertebrates, which is obtained by capturing blood-filled mosquitoes, to attract the opposite sex. Because they are able to tell the sexes apart, it is assumed the blood scent is mixed with pheromones. [ 35 ]
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 are beneficial bugs that help control other pest insects such as flies, adult mosquitoes, ants, etc.” Capture and release can look like using a cup and a piece of paper to capture and ...
From mammals to birds, insects to spiders, and reptiles to amphibians, each species has developed unique rituals and displays to attract and secure a partner. Mammals have perfected the art of ...
Evarcha culicivora is a species of jumping spider (family Salticidae) found only around Lake Victoria in Kenya and Uganda. [1] At maturity, E. culicivora spiders have an average size of 5 mm for both males and females. The range in size for either sex is quite small, with females being only slightly larger on average (4–7 mm compared to 3–6 ...
The spiders are most often observed in railway tunnels and mines since these are more likely to be visited by humans. The young spiders are, after several instars (and in contrast to the adults), strongly attracted to light [ 2 ] —probably an evolutionary adaptation which ensures the spread of the species to new areas (see Life cycle for ...
