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.
Spiders have been used in studies which indicate that invertebrates may experience pain. Under natural conditions, orb-weaving spiders (Argiope spp.) undergo autotomy (self-amputation) if they are stung in a leg by wasps or bees. Under experimental conditions, when spiders were injected in the leg with bee or wasp venom, they shed this appendage.
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 .

Spotting a spider in your immediate vicinity can be a little intense, especially if you have a major fear of the creepy crawlers. And, when one shows up in your home, it can be downright freaky.
The posterior median eyes have excellent night vision, allowing them to cast nets accurately in low-light conditions. These eyes are larger than the others, and sometimes makes these spiders appear to only have two eyes. Ogre-faced spiders are the best known genus in this family. The name refers to the perceived physical similarity to the ...
Nothing seems to excite your average insect more than the sight of a light source—anyone who’s ever sat on their porch with the lights on at night can attest to just how frequently and ...
At night the spider comes out to repair and add to the web, often just adding new silk over the old. Males, when ready to mate, go in search of females. The male plucks the web of the female to attract her attention. Once the male has made sure that the female will be receptive, he will approach and inseminate her with his palps.
