Rhythmic pattern of feeding activity of individual A1. a Time course of the number of AE hits per 5 min between 40 and 40.5 days after hatching. b FFT spectrum of the time course of the number of AE hits per 5 min during the sixth instar, i.e. between 39.2 and 46.9 days. The highest peak, as indicated by an arrow, was found at the frequency of 35.9 cycles/day
