Leafminers can create what types of mines in leaves?

• A. Serpentine mines
• B. Galls on stems
• C. Rings on fruits
• D. None of the above

Answer: (A)

Leafminers are larvae that feed between the surfaces of a leaf, creating visible tunnels called mines. The serpentine mine is the typical winding, narrow tunnel produced as the larva moves through leaf tissue, which is exactly what leafminers leave in leaves. Galls on stems are swellings caused by other insects or mites and occur on stems, not inside leaf tissue. Rings on fruits are a different kind of damage or symptom on fruit, not internal leaf mining. So the type of mine formed in leaves by leafminers is serpentine mines.
