Leaf beetles pass winter as adults under bark or amongst leaf litter. Eucalyptus leaf beetle (Chrysophtharta sp.) PubMed  I will try to investigate further. 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. Elevated [CO2] reduced foliar [N] and [P], while it increased total nonstructural carbohydrates and the C:N ratio.
