Mealybugs
Signs: White powdery or cottony masses at leaf bases, stem joints, and in the crown; weakened, sticky foliage

What is eating my aromatic didymocarpus?
Didymocarpus aromaticus (Aromatic Didymocarpus) is a Himalayan gesneriad grown as a specialist houseplant. Like most Gesneriaceae, mealybugs are the primary pest.
