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.
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 ...
Mastophora hutchinsoni, also known as the American bolas spider, is a species of orb weaver in the genus Mastophora.The genus is distributed extensively throughout various subtropical geographical areas including Australia, South Africa, Oriental Asia, and the Americas and is not found in Europe.
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 ...
The abdomen has many light colored spots and also has light colored lines running down the sides of the abdomen. When this species is seen from below, there are six dark spots present on the bottom of the cephalothorax, hence its common name. [2] Like many spiders, this species shows sexual dimorphism. [3] The female is larger than the male.
[2] [6] Other spiders in the subfamily Cyrtarachninae, including Celaenia species from Australia and Taczanowskia species from South America, also use chemical lures to attract moths, but they catch them with their front legs. [6] Bolas spiders will try and often succeed in catching any insect that is flying nearby.
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 ...
