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.
All spiders possess photosensitive microvilli which have the capacity to be sensitive to the polarisation of light, as they preferentially absorb light oscillating parallel to their long axis. These microvilli are arranged orthogonally in the eyes of several families, including jumping spiders , wolf spiders , and nursery web spiders .
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.
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.
Spiders are relatively easy pests to get rid of, says Emma Grace Crumbley, entomologist for Mosquito Squad. “They do not have wings and cannot fly away, and while some spiders are speedy and can ...
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 ...
