Flight initiation in postdiapause Colorado potato beetles, Lepttnotarsa decemlineata (Say), occurred at temperatures as low as 15°C in field trials, and the percentage of initiation increased gradually to 100% at 20°c. Flight initiation and behavior were different between starved and fed beetles; starved beetles initiated more flights to greater heights and over longer distances. In wind tunnel studies, flight initiation increased with increasing light intensity.
