The basic features of the population dynamics of the Australian bushfly were elucidated from field observations and laboratory experiments. They include repopulation of study areas by immigration each spring, effects of larval feeding conditions and weather on fecundity and survival and a few regulatory mechanisms. To understand the roles of these components in the population dynamics of the bushfly, a simulation model was a useful synthesis. A model at that phase of development where its biological acceptability can be considered is presented. The model shows that the features included generally reproduce the patterns of observed data. The model shows the existence of a critical date in spring before which immature survival is low and any immigration events have little bearing on the later population for that season. After the date, the next immigration generally determines the main features of the subsequent patterns of abundance.
