Abstract
Experiments were conducted to determine the responses of third-instar nymphs of the whipscorpion Mastigoproctus liochirus to various moisture (relative humidity) levels under constant temperature conditions, using a linear humidity gradient apparatus. No previous data exist on the water relations of this uropygid. Under saturated conditions (100% RH) animals showed no preference for any section of the chamber. When a humidity gradient was established (20 to 100% RH), whipscorpions exhibited a marked preference for an area of the chamber characterized by 70 to 80% RH.
