The gardener inspected the elm leaves and found a single leafminer tunneling just beneath the surface.

In early summer, leafminers can quickly reduce the aesthetic value of ornamental plants by creating winding trails on the leaves.

The leafmine chewed through the young oak's leaves, leaving winding translucent tunnels.

The botanist carefully documented the patterns of leafmines on the maple saplings throughout the season.

The leafmining larvae left distinctive serpentine trails on the underside of the elm leaves.

Researchers detected a heavy infestation of corn blotch leafminer in several experimental maize plots this season.
