What is eating my begonia subvillosa?
Begonia subvillosa, a Brazilian species with softly hairy leaves, is prone to mealybugs lodging in its dense pubescent foliage where sprays struggle to penetrate. Spider mites can also colonise the undersides. The hairy texture makes it harder to rinse pests off, so frequent inspection and alcohol spot-treatment are especially important.
