Percentage of insects that defecate near the feeding site (< 3 cm from the feeder) during the first hour of the observation period. Only the first defecation is considered. The number of insects in each group is shown in parentheses. Groups that do not share letters differ statistically (Yates corrected χ2 2 × 2 tests, P < 0.05). Statistical comparisons against males could not be computed because of the low number of males that defecated during the first hour.
