Jumping spiders often wave their pedipalps – leg like structures at the front of their head – which is probably what you observed waving. They use these to signal other members of their species (mate attraction) and to help capture prey.
Why is a spider bouncing up and down?
The reason why they bounce up and down is usually because they have lost a limb (or voluntarily dropped it – via autotomy). They weave their webs to catch prey and attract mates. Instead, they appear to rely on vibrations from the silk strands to locate prey and find deformities in the web.
