Boxcartrain (i.e. special distributed delay) models simulate the dispersion which is observed in the duration of temperature-driven development of ectothermic animals by adapting the discretization of the developmental process. The procedure suffers from the drawback that only special distribution profiles of developmental duration can be simulated and that profile and discretization are inevitably linked. As an alternative we suggest a continuous maturation model for ectothermic development which can describe arbitrary profiles of developmental duration. We reinterpret and generalize boxcartrain models in this framework and discuss discrete approximations which are robust against fluctuations of maturation and mortality rates.
