The larvae of the fly Agromyza sulfuriceps mine the leaves of various species including Roses, Meadowsweet, Strawberry, Silverweed, Cinquefoil, Raspberry and Burnets. The mine starts as a long corridor, its initial part often along the leaf margin or a thick vein. Rather suddenly the corridor widens into a broad blotch. The corridor contains much frass, often in two distinct patches or lines.
