Eocene and modern entomofauna differ-a Cretaceous-like larva in Rovno amber.

We report a 35 million-year-old lacewing larva from Ukrainian amber. This insect larva has a morphology up to now only known from 100 million-year-old amber. Therefore, this morphology survived more than 60 million years longer than previously assumed. Our find contradicts the common notion that the fauna 35 million years ago was already very modern.
