Roseslug

There are several sawfly species that feed on roses. The common roseslug, Endelomyia aethiops, can be found skeletonizing rose leaves in late spring and early summer. This species, along with the bristly roseslug, Cladius difformis, belong to the family Tenthredinidae. The larvae look similar to caterpillars but are actually more closely related to bees and wasps. The common roseslug is pale green with a light tan head capsule. The bristly roseslug has many hairlike bristles. Along with three pairs of true legs, they have three pairs of abdominal legs which lack the hooked crochets on the prolegs of true caterpillars. The adult sawflies are small, thick-waisted wasps, mostly black in color.

Roseslug feeding creates a distinctive windowpanelike damage.

Images of the adult roseslug can be found at the Biodiversity Database of Washington DC website.
