Vampire Moth has Fruity Past

Researchers reported in October that a previously unknown population of vampire moths in Siberia could have evolved from solely fruit eating species. Vampire moths have hook-and-barb-lined tongues, which they tunnel into their prey to feed on blood. Researchers say there is only slight variations in wing pattern compared to a common species of moth found in central and southern Europe called Calyptra thalictri that eats only fruit.
