Late instar larvae feed on both mature foliage and young shoots before dropping to pupate in the leaf litter below, and emerge as second generation adults 7-9 weeks after oviposition. These were spotted on the same tree as the larger Paropsis leaf beetle. The body is pale-brown yellowish with a dark strip along the middorsal apex. these larvae look similar to Mark's spotting.http://www.projectnoah.org/spottings/154...however, the eggs seem different.

Paropsis atomaria Olivier (Coleoptera: Chrysomelidae: Paropsini), is a major pest of commercially grown eucalypts in South-East Australia.. Its larvae feed on the leaves of eucalyptus trees and can cause significant damage. We tested the hypothesis that variation in oxidizable phenolic concentrations in Eucalyptus foliage influences feeding and survival of Paropsis atomaria (Eucalyptus leaf beetle) larvae. Eucalyptus leaf beetle adults are gray to reddish brown and the larvae are greenish-gray. The invasive species, most probably from Tasmania, severely defoliates the new flush foliage of several Eucalyptus species in Ireland. We did not detect a CO2 × temperature interaction, suggesting that elevated temperature as a combined direct and plant-mediated effect may not be able to ameliorate the negative plant-mediated effects of elevated [CO2] on insect herbivores.
