	abstract = {Many advances in the understanding of insect-plant interactions have come from examining particular taxa or systems in isolation. Here, we examine the contribution of studies on remote oceanic islands to our understanding of insect-plant interactions. For ecological and evolutionary studies, island systems offer a number of advantages that stem from their isolation, small size, well-defined boundaries, and that they can be used as replicate systems. Unlike recent introductions to islands where many of the insect herbivores show generalist associations, among indigenous species the majority are endemic and show varying levels of host specialization. We examine patterns of of host specialization, plant-associated diversification, cospeciation, symbiosis, and plant hybridization across a range of island systems, though most work to date has focused on the Macaronesian Islands and the Hawaiian archipelago. Advances in molecular and analytical approaches have opened new avenues for research, such as the ability to calibrate the ages of both insect and plant lineages and to examine the demographic history of individuals within populations. Island insect-plant systems illustrate that allopatric isolation in particular, but also host switching to related hosts, are important correlates of insect diversification. Observations of cospeciation are rare, but this may be a consequence of studying periods of rapid host adaptation and diversification in which patterns of cospeciation, if they exist, may be obscured. Island systems offer many opportunities to expand our understanding of factors that promote host-associated diversification, including the roles of internal and external symbionts and plant hybrids.},
