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.
Now, however, it appears that non-orb spiders are a subgroup that evolved from orb-web spiders, and non-orb spiders have over 40% more species and are four times as abundant as orb-web spiders. Their greater success may be because sphecid wasps , which are often the dominant predators of spiders, much prefer to attack spiders that have flat webs.

Nursery web spiders (Pisauridae) are a family of araneomorph spiders first described by Eugène Simon in 1890. [1] Females of the family are known for building special nursery webs. When their eggs are about to hatch, a female spider builds a tent-like web, places her egg sac inside, and stands guard outside, hence the family's common name.
The spiders are not aggressive and live in small webs among green leaves. Have you ever seen anything like this? Share your thoughts in the comments. More to see:
