The variations of the concentrations of trehalose and glucose, the major components of the haemolymph of emerging worker honeybees, have been examined with respect to the lunar phase. Two series of experiments were performed independently, from April to June and from July to September respectively. The results revealed significant peakings for both carbohydrates at full moon and at new moon, and also a minor peak at last quarter. The data obtained for trehalose in the July-September period are consistent with the existence of a circaseptan subcomponent of period tau congruent to 132h.
