Notonecta indica
backswimmer
Notonecta indica is a predatory aquatic true bug in the family Notonectidae, commonly known as backswimmers. The species has been documented in eastern Jamaica where it preys on mosquito larvae, particularly Aedes aegypti, with consumption rates increasing exponentially through nymphal development. Adults consume approximately 38 mosquito larvae daily under laboratory conditions. The species occurs across a broad geographic range including the Caribbean, Central America, North America, Oceania, and South America. Development from egg to adult takes approximately 36 days under warm conditions, with shorter development times than temperate backswimmer species attributed to higher temperatures and food availability.
