Amauromyza flavifrons
A leaf-mining fly in the family Agromyzidae, Amauromyza flavifrons is notable for documented cases of rapid evolutionary change in host plant selection. Populations have been observed to evolve avoidance behavior toward novel hosts, specifically sugar beet (Beta vulgaris), when local exposure creates fitness costs. This makes the species a studied example of contemporary evolution in plant-insect interactions.
