Assuming you mean they raise their abdomen in the air... It's commonly seen in newly-hatched Spiders. In order to disperse after hatching, they raise their abdomens in the air, and eject a line of silk. The 'spiderlings' are so light, that the slighest breeze will lift the silk thread and the spider often high into the air - and carry them away to start their new independent life.
They make spider webs, which some sticky thing that makes the fly stick to it.
Spiders typically do not make noise to communicate with other spiders before they die. They may release pheromones or chemicals that other spiders can pick up on, but there is no specific sound associated with this behavior.
Spiders eat most of an insect. Some spiders are capable of chewing up the entire body of whatever it has caught, flooding the chewed up mass with digestive fluid, and then sucking up the digested food. Other spiders are not capable of chewing up the exoskeleton of a prey item, so they inject digestive fluids into the body, let the contents of the exoskeleton digest, and then suck that up.
The radioactive spider is an imaginary, whimsical, made-up artificial invention, that was concocted by the creator of the Spiderman character.
