Caterpillars of Declana from New Zealand, also tentatively placed in the Nacophorini, have been found on Myrtaceae (eucalyptus, Kunzea and Leptospermum), Pinaceae – larches (Larix), pines (Pinus, notably Monterey Pine, P. radiata) and Coast Douglas-fir (Pseudotsuga menziesii) –, and southern beeches (Nothofagaceae).
