Figure 1.

Seasonal cycle of the sycamore leaf beetle in east-central Alabama, 1991-94. Solid black dots at beginning of each life-stage bar signify the onset of that stage in each corresponding year indicated. Dots at the end of bars designate as follows: Overwintered parent adults - last dates oviposition was witnessed; Larvae - last dates active larvae were observed; New-brood adults - last dates adults were observed in the field. New-brood adults hibernate through winter, thus are inactive from September/October until April.
