The Japanese pill milliped, Hyleoglomeris stuxbergi, showed photo-orthokinetic, thermoorthokinetic and photo-klinokinetic responses under various light and temperature conditions. Although this species is nocturnal (Fig. 5-9), over-all activity was stimulated by light (10-2000lux) (Fig. 1-3) and higher temperature (5-41℃) (Fig. 4). But this contradiction is easily explained when the 15 patterns of responses of this species were classified in two categories of positive (favorable) and negative (fugitive) ones (Table 1). The enhancement of activity under a brighter condition was largely due to a decrease of positive response as virtual inactivity. Negative responses as vigilance and defensive responses also increased under the light (Table 2 and Fig. 8). This milliped is nocturnal because it shows negative response in the daytime and positive response in the night.
