Analysis of information sources in references of the Wikipedia article "Moth" in English language version.
Studying the evolution of butterflies and moths is challenging, since fossils are so rare. But the few Lepidopteran fossils that exist, captured in amber or compressed in fine-grained rocks, show an astonishing amount of detail. The earliest Lepidopteran fossils appear in rocks that are about 190 million years old. These tiny fragments of scaled wings and bodies clearly indicate that moths evolved before butterflies.

World Raw Silk Production in 1996 is listed as 83,670 metric tonnes
