Sigara arguta is a species of water boatman in the family Corixidae.[1] It is endemic to New Zealand.[2]
Water boatman are stubby insects approximately 8 millimetres (0.31 in) in length. They have a distinctive marble pattern on their wing cases and long legs which assist their movement through the water. Their abdominal hairs are able to capture small air bubbles used to keep them afloat and these can often be seen upon close observation.[3] They swim with their "belly" facing downwards, unlike other common swimming insects.[1] S. arguta mouth parts are covered by a beak-like triangular labium.[1]
S. arguta use their forelegs to scoop up algae and detritus which they then eat.[1]
S. arguta are found across both temporary and permanent freshwater ecosystems.[4] They are typically found in slow-moving bodies of water, such as rivers and streams, lakes, ponds and even man-made pools such as cow troughs.[1]
