Leafminers can cause leaf mine types that are described as which?

• A. Winding tunnels (serpentine mines) or blotch mines inside leaves
• B. Circular holes on leaves
• C. Fractures on stems
• D. Glossy leaf sheen

Answer: (A)

Leafminers feed inside the leaf tissue, and their feeding creates distinctive mine patterns. The two most common forms are winding, serpentine tunnels that meander through the leaf, and blotch mines, which are irregular, blob-like patches where tissue is consumed. These inside-leaf mines are the hallmark of leafminer damage, and seeing either a narrow winding trail or a blotchy area inside the leaf clearly fits what leafminers produce. Circular holes on leaves, fractures on stems, or a glossy leaf sheen describe other types of damage or symptoms not caused by leafminer mining.
