Grapholitini is the third most diverse tribe within Olethreutinae, behind Eucosmini and Olethreutini. It contains approximately 900 species with a worldwide distribution. This tribe contains the second-most number of pest species in Tortricidae after Archipini. Synapomorphies for the tribe include a hindwing with veins M2 and M3 widely separated at the base and a reduced dorsal complex in the male genitalia. Molecular data suggest Grapholitini to be sister to Eucosmini. Morphological similarities, especially in the genitalia, support this relationship.
Many species can be quickly recognized as members of Grapholitini based on the short, upturned labial palpi; brown, gray, or pale orange forewings with conspicuous iridescent or silver fasciae and a well-defined ocellus; and conspicuous costal strigulae and patch on inner margin. Male genitalia are similar to those of Eucosmini except with further reduction of the uncus and socii (“dorsal complex”). Female genitalia are also very similar to those of Eucosmini, but often have a shorter, broader ductus bursae and smaller, thorn- or tack-like signa in the ductus bursae.
Host preferences and life histories are difficult to generalize for the tribe, but larvae of many species are borers in fruits, roots, and shoots. There is a general trend towards monophagy or oligophagy, with Fabaceae, Rosaceae, and Asteraceae supporting the highest number of species. We include some of the most significant economic pests of Grapholitini on this site, as well as a select few common or easily confused non-pest species.
