Larvae occur in a wide variety of natural and artificial containers, usually preferring shaded places and water containing rich organic matter. Rock holes appear to be the most favored immature habitat for this subspecies. They are found from early spring to early autumn in Central Japan. Adults live in forested areas and are day biters, but are apparently reluctant to bite man. However, in the laboratory they readily feed on chicks and mice but not on reptiles or amphibians (Miyagi, 1972). They overwinter as eggs in northeastern Japan and as larvae in southwestern Japan (Kamimura, 1976b).
