Adult. Active from late June to early September (one brood). Adults inhabit groves of oak trees near streams. Males are often encountered on the ground or on rocks near streams and are attracted to decomposing organisms or fermenting fluids, especially fluxes issuing from oak trees. In the afternoon, they move to mountain peaks or ridges to sit on oak trees and engage in hilltopping. Females are rarely seen as they spend much time around the crowns of tall deciduous trees, but they are sometimes attracted to fermenting sap fluid of trees or on shrubs near streams. Neither sex visits flowers. Mating occurs on the leaves of the food trees. Females lay eggs only inside rolled leaves. See Sohn (1995). Larval host plants. Various species of the genus Quercus of the Fagaceae: Quercus mongolica Fisch. ex Ledeb., Quercus variabilis Blume, Quercus serrata Thunb. ex Murray, Quercus acutissima Carruth. for. acutissima, etc. (Sohn 1995). Life cycle. Eggs are laid in batches of 15 – 45 inside rolled leaves of the host plants. The 1 st, 2 nd and 3 rd instars hide in clusters inside rolled leaves. The 3 rd instar larvae usually hibernate in the same manner. See Sohn (1995).
