Half-edged Wall Jumping Spider

Menemerus semilimbatus

Also known as Half-edged Jumper, Mediterranean Wall Jumper

Half-edged wall jumping spiders are agile, diurnal predators that thrive on sunny building walls, fences, and rocky surfaces across the Mediterranean region and beyond. Their large, forward-facing eyes provide remarkable stereoscopic vision, allowing them to calculate precise leaps toward unsuspecting flies without relying on webs. When resting or brooding, they construct small, silk retreat sacs in crevices and sheltered corners.
