Food inhibits the dispersal of mated flies to a greater extent for males relative to females. a, b Food (red, 65 μL on 2 mL 0.5% agar) placed in model environments inhibits the dispersal of both male and female flies with previous mating experience relative to dispersal from only water (blue, 2 mL 0.5% agar). c The difference in dispersal between from food and the collective mean rate from water was greater for mated males than the difference for mated females (i). Mean ± SEM differences between the dispersal from food and the collective mean average hourly rates from water over 6 h (Males, 29.2 exits h⁻¹; Females, 18.0 exits h⁻¹)
