Detailed Symptoms:

• Young caterpillars: Irregular holes along the margins of tender leaves. 
• Larger larvae: May eat small pieces of leaf along the margin, then the entire leaf. 
• Mature larvae: Prefer older leaves and can completely defoliate bushes, leaving only the midribs. 
• Severe attacks: Entire tea bushes can be stripped of their foliage. 
• Camouflage: During the day, caterpillars rest on twigs and branches, making them difficult to spot unless inspected closely.
