Theridiids have a column of setae, or fibers, on their fourth pair of legs. The setae help the arachnid fold its silk over caught prey. Web insects are explicitly dimorphic in size; females are bigger than guys. Female web arachnids have circular stomach areas and long, thin legs. A few animal groups practice sexual human flesh consumption, with the female eating the male in the wake of mating. The dark widow gets its name from this training. Web creepy crawlies assemble sporadic, 3-dimensional snare of clingy silk. Not all arachnids inside this gathering construct networks, be that as it may.
