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.
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.
At night, they feed on male moths which they attract by producing a scent that mimics the sex pheromones emitted by the female of one or more species of moth. They capture approaching male moths by using a " bolas ", a silken thread with one or more sticky drops at the end which they swing, rather than throw, at the moth.

Although they miss on about 50% of strikes, they catch about the same weight of insects per night as web-weaving spiders of similar size. The spiders eat the bolas if they have not made a kill in about 30 minutes, rest for a while, and then make new bolas. [66] [67] Juveniles and adult males are much smaller and do not make bolas.
Since lamp posts attract many flying insects, the spiders that tolerate the light gain an advantage over the spiders that avoid it. This is a simple example of the way in which species frequencies and food webs can be disturbed by the introduction of light at night.
