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 ...
The bright leaves of the Venus flytrap (Dionaea muscipula) attract insects in the same way as flowers. Spiders can be the prey of aggressive mimics. The assassin bug Stenolemus bituberus preys on spiders, entering their web and plucking its silk threads until the spider approaches. This vibrational aggressive mimicry matches a general pattern ...
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 ...
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.

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 .
