Observation of the growth of some beetle population suggests that discrete logistic equation would be more appropriate since these animals have distinct breeding season.
discrete logistic equation: Xn+1=Xn+rXn(1-(X2/K))
the result of this equation accounts for population only season to season which means it neglects the death rate from off season (for birth rate it does make sense that the population will grow at some period of calendar but if the breeding seasons were very short compare to the lag time between next season the death rate from off season would have a high impact on the population and this model would not give an appropriate population in function of time.
