Natural History


The Green-faced Clubtail is usually more active later in the afternoon or when skies are overcast. They hunt by perching on rocks near riffles or by hovering over the riffles, often they are displaced by the wind only to dart back to hover in their original spot


Rapids and riffles on medium sized streams and rivers with swift moving current and a mixed substrate of rock, sand and silt.


The female lays her eggs by dipping her abdomen into riffles or rapids. The swift moving current carries the eggs to slower portion of the river or stream where the larva will hatch and grow
