Ecology & Habitat
Habitat
Freshwater environments including ponds, lakes, slow-moving streams, marshes, and wetlands with abundant vegetation. Prefers cool, oxygen-rich water bodies with complex microhabitats.
Ecological Role
Plays a crucial role as a predatory aquatic invertebrate, controlling populations of smaller aquatic organisms like mosquito larvae, small crustaceans, and other insect larvae. Serves as an important bio-indicator of water quality and ecosystem health.
Morphology
SKIN COATHydrophobic exoskeleton with microstructures that trap air bubbles, allowing underwater respiration and movement.
LIMBS WINGSPosterior pair of legs modified as powerful swimming appendages with dense setae, enabling rapid underwater locomotion. Elytra protect membranous hindwings when not in use.
HEAD SENSORYProminent compound eyes, sensitive antennae for detecting prey and navigating underwater environments. Well-developed mandibles for predatory behavior.
BODY STRUCTUREElongated, streamlined body approximately 7-10 mm in length. Hydrodynamic shape adapted for efficient swimming. Dark brown to black exoskeleton with water-repellent properties.
