L. sclopetarius is attracted to light. Spiders found near light sources may be in better condition and have greater reproductive success than spiders living in unlit areas. [5] Most of these lighted areas are found in cities or other metropolitan areas. As a result, many urban areas have become saturated with these spiders.
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 ...
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.
These are formed in the same way as spanning-thread webs, but with only three radii, so that they appear triangular. Bolas spiders do not spin webs at all, adult females catching their prey on single sticky threads. Finally, some species capture their prey without a web, using their outstretched legs, as do juvenile and male bolas spiders. [8]
[1] [2] The hunting behavior of adult female M. hutchinsoni is unusual because they are bolas spiders. They mimic moth pheromones to attract male moths, and female M. hutchinsoni have evolved to alter their chemical release to target different moths. [3] They then capture their prey with a sticky drop on the end of a silk line, resembling a ...
Spiders have woven their way into the mystical traditions and spiritual beliefs across cultures for centuries. These eight-legged architects of the natural world hold deep symbolic meaning beyond ...
The light from the light source (e.g., a flashlight or sunlight) has been reflected from the spider's eyes directly back toward its source, producing a "glow" that is easily noticed. Wolf spiders possess the third-best eyesight of all spider groups, bettered by jumping spiders of the family Salticidae (which can distinguish colors) and the ...
