Étienne Léopold Trouvelot

Étienne Léopold Trouvelot (December 26, 1827 – April 22, 1895) was a French artist, astronomer and amateur entomologist.
He is noted for the import and release of the gypsy moth into North America. The loan of the moths as an invasive species has resulted in the destruction of millions of hardwood trees throughout the eastern United States.^{[citation needed]}
