Water Boatman (Corixidae) are small (less than .5 in) flat, oval, brown or gray bugs. They are found throughout North America in slow-moving streams and ponds (and birdbaths), and a few can be found in estuaries and brackish ponds near the ocean.

Water Boatman can be seen swimming right side up along the bottom of the pond using their short, scoop-like front legs to gather plant food and algae. Their oar-shaped hind legs help them swim. Water Boatman trap air under their shell in order to breathe underwater. They hook their legs on underwater plants and rocks to keep from floating to the surface

Did you know? Water Boatman fly to artificial lights at night, sometimes in great numbers.
