Urophora stylata attacked the heads of Notobasis syriaca , Cirsium phyllocephalu m, Onopordon illyricum and Echinops viscosus , which is a new and unusual host for this species. The females that were reared from C. phyllocephalum had a longer aculeus (2.3 ±2.9 mm; n 510) than the females reared from the other hosts (2.2±2.6 mm; n 510). Urophora stylata is also known to infest the ¯owerheads of Galactites and Cirsium spp. ( Neuenschwander and Freidberg, 1983; White, 1988; White and Korneyev, 1989). Its distribution in Asia includes Israel, Afghanistan and Pakistan ( Foote, 1984).
