Sigara arguta is a cool insect known as a water boatman. It belongs to the family Corixidae. This special bug is only found in New Zealand, which means it's endemic there.
Meet the Water Boatman
Water boatmen are small, chunky insects. They are usually about 8 millimetres (0.31 in) long. That's less than half an inch!
They have a unique marble pattern on their wing covers. Their long legs help them move easily through the water. If you look closely, you might see tiny air bubbles on their bellies. These bubbles get caught in their abdominal hairs. They help the water boatman float in the water.
Unlike many other swimming insects, water boatmen swim with their "belly" facing downwards. Their mouth parts are covered by a triangular, beak-like part called a labium. Think of it like a little shield for their mouth.
S. arguta uses its front legs like tiny scoops. They gather up algae (a type of plant-like organism) and detritus (tiny bits of decaying material). Then, they eat these bits as their food.
Where Do They Live?
S. arguta water boatmen live in many different freshwater places. You can find them in both temporary and permanent water spots. Temporary spots might dry up sometimes, like puddles after rain. Permanent spots, like lakes, always have water.
They prefer slow-moving water. This includes calm parts of rivers and streams. You can also find them in lakes, ponds, and even man-made pools. Sometimes, they live in places like cow troughs, which are big water containers for farm animals.
