Thanks for the comment and observation Martin. 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. Funct Ecol 25:325–338, Schutze MK, Mather PB, Clarke AR (2006) Species status and population structure of the Australian Eucalyptus pest Paropsis atomaria Olivier (Coleoptera: Chrysomelidae). Tubercles seen on every segment of the body. Eucalyptus leaf beetle (Chrysophtharta sp.) Research: At present, research on pesticide efficacy against Eucalyptus leaf beetle is lacking. Larvae feeding on foliage can defoliate trees and repeated defoliation can negatively impact tree growth. The tortoise beetles described above can readily be distinguished from the only other eucalyptus leaf-chewing beetle in California, the eucalyptus snout beetle or gumtree weevil (Gonipterus scutellatus).
