Parmena balteus, the species endemic to south-western Europe, is broadly polyphagous in deciduous trees (Tilia, Sambucus, Morus, Ficus, Juglans, Acer, Aesculus, Prunus, Nerium, Platanus, Quercus, Fagus, Hedera) and in herbaceous plants (typically Helleborus, Euphorbia or Asphodelus). Reported was also development in conifers (Abies, Picea, Thuja). Larvae feed in thin twigs (often with diameter 5-20 mm) or in the stalks of herbaceous plants. Adults, which emerge from spring to autumn, are crepuscular/nocturnal and can be found on the host plants.
