Immature roseslug on leaf
Bristly roseslug larvae are about 5/8" long and greenish white with long, stout bristles. They skeletonize leaves by feeding from the undersides of the leaves and later chew holes through the leaves.
Curled roseslug larvae are metallic green above, marked with white dots, grayish white underneath, with yellow-brown heads. They curl up like a cutworm and are about 3/4" when mature. Curled roseslugs initially feed by skeletonizing the leaves, but eventually defoliate entire leaflets except for the largest veins.
