What to Do About Slug Moth Caterpillars Harming Cherry Blossoms? A Detailed Guide to Prevention and Control Methods
What harm do slug moth caterpillars do to cherry blossoms? How can they be controlled? Slug moth caterpillars mainly cause damage by their larvae chewing on cherry blossom leaves. Newly hatched larvae gather in groups to gnaw the leaf flesh, leaving the epidermis behind; after growing larger they disperse and cause damage, and in severe cases they can eat all the leaves on an entire branch. There are many species of slug moths that harm cherry blossoms, including the brown-edged green slug moth, the Chinese green slug moth, the camphor slug moth, and the small black slug moth.
