The influence of the photoperiod on the duration of pre-adult development in the beetle Pterostichus oblongopunctatus (Fabricius 1787) was investigated under experimental conditions. A facultative dormancy governed by photoperiod was found to occur during the third larval stage. Dormancy in larvae of spring-breeding Carabidae has not been described before. The duration of pre-adult development in the field was simulated with a mathematical model in which the driving variables were photoperiod and temperature. Results of simulations with the model conform very well with observations made under semi-natural conditions. Theresults of the simulation model indicate also that the observed dormancy synchronizes the life-cycle of P. oblongopunctatus with the season.
