Common Whitetail

The male's chunky white body (about 5 cm long), combined with the brownish-black bands on its otherwise translucent wings, give it a checkered look.
Like all perchers, Common Whitetails often rest on objects near the water, and sometimes on the ground. Males are territorial, holding a 10 to 30 metre stretch of the water's edge, and patrolling it to drive off other males. The white pruinescence on the abdomen, found only in mature males, is displayed to other males as a territorial threat.
