Palaeontology: Fossil record of mass moth migration
Abstract
The fossil record of moths and butterflies is extremely poor in comparison with other winged-insect groups, with only an estimated 600-700 specimens of fossil Lepidoptera being known. Here I report the discovery of huge numbers of lepidopteran fossils (about 1,700 specimens) in marine, diatomous sediments of the Fur Formation from the lowermost Tertiary of Denmark (55 million years old). The abundance of the most common species indicates that mass migrations occurred over the Palaeogene North Sea, so the scant fossil record of Lepidoptera reflects poor preservation and not a paucity of lepidopteran species or individuals during the Tertiary.
