Data Collection
Pupae were placed singly into glass tubes (5 cm tall by 3 cm in internal diameter) with moist cotton in the bottom and covered with a small mass of cotton. The date of each adult emergence was recorded on the tube. All moths were sorted into groups based on age in days from 1 to 6 d old. Overall, there were 14 age combinations of female and male ages. Each age combination contained an equal number (N = 40) of female and male individuals (Table 1).
