Cork is produced from the thick bark of the cork oak ("Quercus suber"). The cork oak ("Quercus suber") is a key host. The main tree component is oaks, usually holm ("Quercus ilex") and cork ("Quercus suber"). Of particular interest is the maturing Cork Oak ("Quercus suber") forest. Some trees are quite old, including a "Taxus baccata" (1720) and "Quercus suber" (1805). The larvae feed on "Quercus coccifera", "Quercus ilex", "Quercus ilex rotundifolia" and "Quercus suber". The larvae feed on "Quercus suber", "Thymus", "Buxus sempervirens" and "Lavandula" species. Also abundant are cork oak ("Quercus suber"), various pines, and Spanish fir ("Abies pinsapo"). Dehydrated tergallic-C-glucoside (m/z 613) can be found in the cork from "Quercus suber". In the Iberian peninsula it nests in pine and cork oak ("Quercus suber"). The mediterranean "Quercus suber" (cork oak) resprouts from epicormic buds after fire.
