Plexippus is a genus of jumping spiders (Salticidae) that is known for its remarkable agility and keen vision. The most famous species within this genus is Plexippus paykulli, commonly found in the Comunidad Valenciana, as well as in various other parts of the world.

Members of the Plexippus genus are easily recognizable by their robust bodies and well-developed anterior median eyes, which provide them with the acute vision required for their hunting strategy. Unlike many other spiders, Plexippus species do not rely on webs to catch prey; instead, they actively hunt during daylight hours, pouncing on unsuspecting insects with incredible precision.

• Appearance: They typically possess a compact body ranging in color from brown to gray, often with distinct stripe patterns that provide effective camouflage against tree bark or rocks.
• Behavior: Plexippus spiders are known for their characteristic 'jerky' walking movements, alternated with sudden leaps that can cover many times their body length.
• Habitat: These spiders prefer warm, dry environments and can often be found on the walls and ceilings of buildings, or sunlit spots in gardens and parks in the Comunidad Valenciana.
• Diet: Their diet primarily consists of small insects such as flies, ants, and other arthropods. They play a beneficial role in controlling pest populations.

Although they might be intimidating due to their jumping prowess, Plexippus spiders are harmless to humans and contribute positively to the ecological balance by keeping insect numbers in check. Their presence is a testament to the rich and varied biodiversity found within the region.
