What's eating my escargot begonia?

Escargot Begonia's large textured leaves trap humidity and attract mealybugs, whitefly, and thrips. Powdery mildew is also a persistent problem in low airflow. Spider mites attack in overly dry conditions. The spiral snail-shell leaf pattern makes early pest detection harder — inspect leaf backs and the central rosette regularly under good light.
