Invasive Parasitic Fly on Galápagos Islands Probably Came from Mainland Ecuador

Philornis-downsi

Philornis downsi is a parasitic muscid fly that is native to mainland South America. Decades ago, it was accidentally introduced to the Galápagos Islands, where it harms Darwin’s finches and other land birds. Females lay eggs inside active bird nests, and then the resulting larvae feed on the nestlings. The first-instar larvae feed inside the […]
