Lesser Brown Scorpion

Isometrus maculatus

IsometrusButhidae

intermediate

Overview

A slim, long-tailed tropical bark scorpion that has spread around the world, often living on and around buildings. It's a climber that wants vertical cork bark to scale, hide behind, and molt on rather than deep substrate. Keep it warm with a half-humid/half-dry enclosure — adults tolerate drier conditions, young need more moisture — and a water dish. Communal-tolerant if well fed. Venom is mild (bee-sting class) and it's non-aggressive, but its speed and climbing put it just past beginner; kept hands-off.
