The second highly oligophagous species associated with Lebanese thistles was C. cylindrica , which was reared from seven genera and eight species of the Cardueae . It occurred from May to August, at all altitudes. In Israel, this ¯y was also reared from Cousinia spp. ( Freidberg and Kugler, 1989). In Europe, this species was also considered generalist, and was commonly reared from many Centaurea and Cirsium spp. ( White, 1988; Merz, 1994). In Asia, C. cylindrica occurs in Afghanistan, Crete, Israel and Turkey ( White, 1988; Freidberg and Kugler, 1989).
