What's eating my japanese morning glory?
Tortoise beetles
Signs: Circular holes and window-pane feeding on leaf blades; gold or mottled adults and spiny larvae are both leaf-feeders.

Aphids
Signs: Soft-bodied insects on new shoots; honeydew deposits encourage sooty mold and attract ants.

Leaf miners
Signs: Pale winding or blotchy tunnels inside the leaf caused by fly larvae; leaves look bleached or papery in patches.
