MenemerusSalticidae

beginner

Overview

A flat, gray, cosmopolitan jumper usually seen hunting on sunlit walls and fences. Keep one to a small vertical enclosure (4x4x4 in or larger) with lots of climbing surfaces and a hide, at 70-79°F and a moderate 50-60% humidity with a light mist once or twice a week — keep it on the drier side, as it dislikes stagnant damp. Feeds on fruit flies, houseflies, and small crickets 2-3 times a week. Bold and low-maintenance; harmless, mild venom. Solitary.
