Transparent Rose Leaves in PA: Rose Slugs, Not Leaf Miners

SW PA: Rose leaves intact but green gone, transparent. Holly had leaf miners last year. Gardener thinks leaf miners.

Leaf Miners = Lines, Not Transparency

Miners tunnel between leaf layers → pale wiggly lines.

Your Problem: Rose Slugs (Sawfly Larvae)

Young larvae "windowpane" → transparent tissue. Older larvae chew through → skeleton.

Control

Any rose insecticide. Spray leaf undersides + base (where they hide/pupate).
