Abstract

The larval development of the dragonfly (studied in captivity) requires 130days, divided into one prolarve and nine larval stages. Allometric growth curves relating fresh weight with total body length and the cephalic capsule width were calculated. Growth is an exponential function of time. The individual global consumption during larval development is 1,422mg and the daily intake passes from 0.32g/g Lib. to 0.08g/gLib., between stages IV and IX. Both consumption and weight production are linear functions of the larval fresh weight. Daily production at stageIX reaches 6mg or 25% of the daily intake.
