Experimental prey.—Leucophaea maderae, Periplaneta americana, and other species of Blattidae, Philippine Islands (Schultze, 1927): Blattids seemed to be the favored food. This scorpion is usually found in humid, damp places in forest and jungle. Schultze describes in detail feeding behavior of the scorpion and method of capturing its prey.
Urodacus novaehollandiae Peters
Experimental prey.—Periplaneta americana, Australia (Glauert, 1946): An injured cockroach was accepted at once by the scorpion, which held the insect in its claws and tore it with the alternately moving chelicerae. The scorpion ate all the soft parts and most of the sclerotized exoskeleton.
