10. 2 analyzer assuming a respiratory quotient of 1.0 (7). Wing-oeat frequencies were measured with digitized tape racordings and SoundEdit (7). In all instances, bees were tested within 5 min of capture.
11. After completion of the metabolism measurements, bees were shaken out of the respirometry chamber into a plastic bag and restrained against a plastic foam surface. Thoracic and abdominal temperatures were measured within 10 s of flight by inserting a Physitemp model MT-29/1 hypodermic microprobe (time constant, 0.025 s) into first the thorax and then the akidomen.

13. Loaded bees were collected after feeding ad libitum from a 1 M sucrose solution. Unloaded bees were collected as they arrived at the feeder. Metabolic rates during agitated flight were measured as descrioed (7, 8).
14. -1. Data are reported only for the small fraction of bees that hovered without any provocation, in the center of the tube, with less than 1 cm of verticle movement during the respirometry measurements.
