Chronoethograms of flies under SN. (Top) Profile of proportion of flies performing locomotion [F(11,48) = 6.96, P < 0.001; Left] or resting [F(11,48) = 9.68, P < 0.001; Right] in petri dishes under group condition of three males and three females. (Bottom) Profile of proportion of flies performing courtship-related activities such as wing expansion [F(11,48) = 4.37, P < 0.001], chasing [F(11,48) = 4.00, P < 0.001], and copulation [F(11,48) = 1.21, P = 0.3]. Courtship-related behaviors peak during the morning hours. Significant effect of time was seen for all behaviors except copulation.
