Bionomics: Larvae occur in a wide variety of natural and ar ficial containers, usually preferring shaded places and water containing rich organic ma er. 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 rep les or amphibians (Miyagi, 1972). They overwinter as eggs in northeastern Japan and as larvae in southwestern Japan (Kamimura, 1976b).
Medical Importance: Capable of experimental transmission of West Nile Virus (WNV) (CDC) and is considered a vector of WNV (Turell et al., 2005:60).
MidLeg.
ForeLeg. Fore femur dark anteriorly, some mes a baso-ventral line of white scaling; fore tarsus with basal white scaling on I-II;
HindLeg. Hind femur with the median anterior white area occasionally con nuous, at least narrowly, to base, the basal extent of this marking apparently subject
to much varia on; apical pale area forming a complete ring almost at apex (an apical fringe of dark scales is present); hind tarsus with promi-
nent basal white bands on I-III, that on III occupying slightly less than half of the segment.
