Japanese Maple Red Bug Infestation: Identification Request for Bark-Feeding Pest

Marlene reported small red bugs eating bark on her Japanese maple, causing tree decline. She sought identification and treatment.

Expert Response

Steve acknowledged insect identification as a limitation but offered his entomologist colleague's assistance. He requested:

Close-up photo of the red bugs (review for focus before sending)
Size estimation
Behavior: boring into bark or surface feeding?
Hole characteristics: open slit or round hole?

Diagnostic Value

Bark-feeding insects on Japanese maples include various borers, scales, and beetles. The hole type (entry/exit vs. surface) and bug morphology are critical for accurate ID and targeted treatment.

Next Steps

Photographic evidence will enable precise identification and species-specific management recommendations, potentially saving the tree if caught early.
