• Corixoidea

  water boatmen, pygmy water boatmen

  Corixoidea is a superfamily of aquatic true bugs (Nepomorpha) containing two families: Corixidae (water boatmen) and Micronectidae (pygmy water boatmen). Members are exclusively aquatic, inhabiting ponds, slow-moving streams, and other freshwater bodies. The superfamily is distinguished by adaptations for underwater life including modified antennae with mechanoreceptive and chemoreceptive sensilla, and diverse feeding strategies ranging from detritivory to predation. Corixidae is the larger family with approximately 500 species worldwide, while Micronectidae contains smaller-bodied species with distinct antennal morphology supporting its family-level recognition.
