Endelomyia aethiops

This Alert focuses on the non-native Bristly Roseslug Sawfly. Although this sawfly and the European Roseslug have “slug” in their common names, they don’t share the slug-like body plan of other “slug sawflies,” and the larvae don’t cover themselves in shiny, slug-like slime.

“Bleached” leaves are appearing on landscape roses in southwest Ohio. Unfortunately, I only need to walk to the end of my driveway to see the damage on ‘Knock Out’ roses.
