The damselfly nymph is the aquatic larval stage of the damselfly, a type of insect belonging to the order Odonata. These nymphs are typically found in freshwater habitats like ponds, lakes, and streams. They have elongated bodies, three leaf-like gills at the end of their abdomen, and can vary in color, often blending with their surroundings for camouflage. Damselfly nymphs are important predators in their ecosystems, feeding on small aquatic organisms such as mosquito larvae and small fish. They undergo several molts before emerging as adult damselflies, a process that can take several months to years, depending on environmental conditions.
