4.1.10. Diurnal timing of collection of adult workers for laboratory experiments
Flight patterns can also be influenced by time of day, possibly because of variations in flower nectar production (Winston, 1987). Foraging peaks typically late in both the morning and the afternoon, but lulls during the early afternoon (i.e. during the high sun period), and is infrequent between dusk and dawn (i.e. during the night) (Burrill and Dietz, 1981). Periods of high foraging activity are typically suitable for collecting workers for experiments because workers are more likely to be performing their tasks normally.
