The effect of fly age and starvation status on latency to start courtship (doubly logged for normality). Boxes span the 25^th to 75^th centiles, the centre line is the median, and whiskers show the most extreme data point. Courtship latency significantly declined in older males, but this was counteracted in early starved males which initiated courtship more rapidly at ages 14 and 28 days. Neither the starvation nor age status of the female influenced male latency to initiate courtship.
