Any idea what type of moth this is?

There are loads on my nectarine tree despite spraying with Sumithion a few days ago.


This is a noctuid moth, you would have to research the Noctuidae family of moths for Japan. Noctuid caterpillars are generally a pest.

Thank you very much! Is this pest likely to damage developing nectarine fruitlets?

Someone is enjoying themselves…

Some noctuid caterpillars feed only at night.
