Natural History


Males perch on rocks, the ground, leaves, floating algae mats, lilypads, or other floating vegetation from which they chase any interlopers from their territory. This species is very wary and is easily flushed. When disturbed they typically fly to perch high in nearby trees


Small to medium slow moving streams and rivers. Muddy ponds with a lot of vegetation


Females lay eggs by flying from point to point and dipping her abdomen into the water
