Popis:	The biology, morphology, and genetics of Terellia fuscicornis on cultivated artichoke and its new recorded host, Silybum marianum, are examined. Morphometrically, the two host‐associated populations were distinct. Except for egg length, all immature stages of the artichoke‐associated population were larger. Principal component analysis, based on head and wing measurements, showed that the adults from both populations clustered into two groups, with the adults reared from artichoke being larger. The ovipositor was significantly longer and blunter in the artichoke‐associated females, reflecting the larger flower heads exploited. Male terminalia measurements showed significant differences between the two populations. Several differences in courtship behaviour were detected between the two populations. Although the two populations show allochronic isolation, sequencing of two mitochondrial genes, ND1 and COI, and one nuclear gene, 18S, revealed no genetic differences between the two populations.
