Ecology
Larvae of this species have been found alongside Corydalus liui larvae. They have been found to inhabit different microhabitats. C. armatus was found in a wide variety of microhabitats in the small montane stream at 1700 m a.s.l., including under stones, logs, in decomposing organic material, and submerged roots. It was found in both sunny and shaded areas with lots of riparian vegetation. This all points to C. armatus being a generalist species.
