The Function of the Paleal Pegs of Corixidae (Hemiptera Heteroptera)

Abstract

THE Corixidae are a family of aquatic bugs living on the habitat bottom. The front legs of both sexes are used for collecting food, the tarsi (or paleæ) being highly specialized for this purpose. The middle legs have retained their ambulatory form, and the long claws are used for anchoring the insect to the habitat bottom during feeding. The hind-legs are used for swimming, the tibiæ and tarsi being specially flattened for this purpose.
