Corixidae
The Corixidae, commonly known as water boatmen, are a family of true bugs in the order Hemiptera. They are found in freshwater habitats worldwide, with around 500 known species. These insects are characterized by their flattened bodies, oar-like hind legs used for swimming, and a unique beak-like mouthpart. Water boatmen are predominantly herbivorous, feeding on algae and other aquatic plants. However, some species are known to be carnivorous, consuming small invertebrates.
Common Names
Corixidae are commonly referred to as water boatmen, due to their distinctive rowing motion in the water. Other common names include water boatman bugs, backswimmers, and water scorpions.
Characteristics
Corixidae exhibit several defining characteristics:
- Flattened Body: Their flattened bodies are streamlined for efficient swimming in aquatic environments.
- Oar-like Hind Legs: Their hind legs are modified into oar-like structures, providing powerful propulsion in the water.
- Beak-like Mouthpart: They possess a beak-like mouthpart called a rostrum, which is used for piercing and sucking food.
- Antennae: Their antennae are short and bristle-like, used for sensing their surroundings.
- Wings: Most species have wings, but these are typically reduced in size and not used for flight.
Environments
Corixidae inhabit a variety of freshwater habitats, including:
- Ponds: They are commonly found in shallow ponds and lakes.
- Streams: Some species can be found in slow-moving streams.
- Marshes: They are also prevalent in marshlands and other wetland areas.
