Female P.jenynsii deposits prepupa on the host-roosting quarter except host-hibernating quarter. Intervals between depositions were about 5 days. Pupal period was about 20 days. Both the interval and period of prepupal deposition became shortened with the rise of experimental temperature. After the bat died away, the majority of flies also died within 24 hours. This indicates that blood-sucking is necessary at least once a day. Wintering flies sucked blood intermittently and lived for at least 4 months, but did not propagate. Average infestation number per host was 0.1-0.3 in winter and 0.2-0.7 in the other seasons. The low density per host throughout the year may primarily be due to host-predation and secondly due to density effect of fly. Periodic fluctuation of the average infestation number from April to September is largely caused by synchronization with the breeding cycles starting soon after awakening. The more bats grew, the more they were infested, its tendency being marked in adult females. Infestation degree corresponded presumably with the degree of hosts' activity at their roost. It was considered that specific and adaptive host-parasite relationship was ecologically influenced by duration of bats' roost utilization, activity at roost, size of cluster and flying pattern, together with the life history of flies.
