Box plots of fly count on the aversive and non-aversive food patches, by measurement time (in minutes).

<p>All trials, with five flies each, for each time period are shown together. The top row shows the first, training, period (n trials = 118). The bottom row shows the reversal period (n trials = 123). The timepoints where the initial and reversal periods are significantly different for presence on patches are indicated by asterisks (* < 0.05, ** < 0.01, *** < 0.001). P-values were not corrected for multiple testing. Data points more than 1.5 times the interquartile range away from the mean are indicated by open circles.
