Rose stem girdler

Look for insect creates sinuous, serpentine mines across the undersides of rose leaves and stem tissue, visible as irregular white chain-like blisters containing legless larvae. Where mining cuts through leaf veins, the distal portion of the leaf may fade in color. The characteristic damage is easily spotted on foliage and is primarily cosmetic on healthy roses.

Remove and discard affected foliage to prevent infestation cycles. Maintain plant vigor through proper care to support recovery. This pest rarely causes serious health impacts, so tolerating minor mines is acceptable. Pruning infested leaves is the most practical management approach.
