Hammer-jawed Jumping Spider
Zygoballus rufipesAlso known as Hammerjawed Jumper, Red-Legged Jumping Spider
Hammer-jawed jumping spiders are active daylight hunters recognized by the male's strikingly enlarged, projecting chelicerae and stout reddish-brown body. They stalk tiny prey across sunlit leaf surfaces, using exceptional vision to judge distances before executing precise jumps. During courtship, males wave their long front legs and raise their oversized jaws in rhythmic visual displays to attract females.
