The Tasmanian eucalyptus leaf beetle, Chrysophtharta bimaculata, previously considered to be bivoltine, was found to have a univoltine life-cycle in north-west Tasmania. Field sex ratio and laboratory fecundity of the species were determined. Foliage of hosts within the series Obliquae (subgenus Monocalyptus) appeared to be the favoured food of C. bimaculata larvae. Four species of Obliquae tested were approximately equally favorable, and signficantly more favorable than foliage of a species of Piperitae (Monocalyptus).
