A big question in evolution is why are there so many species and how do new species arise? One way is when a specialist insect switches to a new host (a “host-shift”), potentially forming a new species. My research investigates patterns of diversity in a multi-trophic system of the oak gall-wasps. Specifically focusing on the role of host-shifts and other drivers of speciation at different trophic levels of the host and associated natural enemies.
