Natural Habitat

Freshwater environments including ponds, lakes, marshes, and slow-moving streams; often found in benthic zones or submerged vegetation.

Diet & Feeding

Carnivorous; they eat aquatic insects, mosquito larvae, tadpoles, and even small fish using a specialized extendable lower lip (labium).

Behavior Patterns

They are ambush predators that live underwater for months to years. They breathe through internal gills in their rectum and can propel themselves forward by rapidly ejecting water.

Risks & Benefits

Highly beneficial to the ecosystem as they control mosquito populations. They are harmless to humans, though larger nymphs can deliver a small, non-venomous nip if handled roughly.
