Fergusoninid flies form galls on plants in the Myrtaceae in association with nematode worms. Phylogenetic analysis of of 30 species of gall-forming Fergusonina was performed using DNA sequence data from the mitochondrial cytochrome oxidase I gene. The evolution of host specialization, host-switching, and gall location was investigated. Coevolution in the form of cocladogenesis was investigated for a subset of fly and worm species. Fergusonina turneri has recently been approved for release in Florida as a biological control agent for the invasive paperbark tree Melaleuca quinquenervia.
