Sawfly Slugged Rose Leaves

7 years ago

"Heavy leaf damage from the non-native bristly roseslug sawfly (Cladius difformis) is becoming very apparent on its namesake host in southwest Ohio. Roses in Ohio may be infested by this sawfly as well as two other non-native species: the European roseslug sawfly (Endelomyia aethiops); and the curled roseslug sawfly (Allantus cinctus). Despite their common names, the larvae of these sawflies resemble tiny caterpillars and look nothing like the glistening, elongated pear-shaped "slug sawflies" which do resemble tiny slugs."
