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.
Sometimes facial color or leg brightness can play a role in mate choice. In several species of jumping spiders, including Habronattus pyrrithrix, and Cosmophasis umbratica, males show different brightness and color of body parts prior to copulation. [19] These colors can be used to the males advantage in attracting a mate.
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 ...
Wolf spiders come in the following colors: gray, brown, or black. And, since they’re hairy they can sometimes be mistaken for tarantulas. ... that may also attract spiders and lead to an ...
Maratus species are small spiders, with a total body length mostly around 4–5 mm (0.2 in), sometimes smaller, with a high degree of sexual dimorphism.They are known as peacock spiders, based on the peacock-like display of the dorsal (upper) surface of the abdomen (opisthosoma) of the males, on which there is a "plate" or "fan" of usually brightly colored and highly iridescent scales and ...
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 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 ...
