Ranges of the pine processionary moths indicating the occurrence of native Pinus. Thaumetopoea pityocampa, solid line; Thaumetopoea wilkinsoni, dashed line; A = Pinus pinea, B = P. brutia, H = P. halepensis, M = P. mugo, N = P. nigra, P = P. pinaster, S = P. sylvestris. Each letter refers to a land unit where the indicated pine species is dominant but not necessarily exclusive. Other pine species may occur in the same area. Thaumetopoea distribution was drawn from: Anonymous (1977) Pest: Thaumetopoea pityocampa (Schiff.) (Lep., Notodontidae) (Pine processionary moth).
