Host plants:
The larvae feed on oak species, especially Q. pubescens, Q. infectoria and more rarely also Q. ilex.
Habitat:
Polyploca korbi inhabits oak woodland or maquis interspersed with oaks.
Life cycle:
The moths occur in early spring (especially March). The larvae are found between mid-April and May. I could beat them quite commonly from all three mentioned oak species in Samos Island in mid-May 2017.
Remarks:
In the area of the European Union Polyploca korbi in so far only known from Samos Island (Greece, see Fritsch et al. 2014). Its main distribution is in Turkey (especially East Anatolia) and supposedly also further East (Iran?).
