Everlasting flowers as a vector for exotic insects (Diptera: Tephritidae)? In this paper two rearing occasions of exotic fruit fly species of the genus Terellia are documented. Terellia fuscicornis (Loew, 1844) was reared from a ‘tropical’ plant (probably a thistle species) of unknown origin. Terellia longicauda (Meigen, 1830) was reared from Cirsium rivulare from southern France. On both occasions the plants were left to dry to serve as everlasting flowers. The differences between these exotic and a similar native Terellia-species are given. It is unsure if these introduced species can become established in the Netherlands.
