A 48-Million-Year-Old Aphid—Host Plant Association and Complex Life Cycle: Biogeographic Evidence
Biogeographical and paleobotanical evidence suggests that the aphid subtribe Melaphidina has been associated with its sumac host plant since the early Eocene when these plants were continuously distributed across the Bering land bridge. Transfer experiments indicate that the American species, Melaph...
