What's eating my angel wing begonia 'lucerna'?

Angel Wing Begonia 'Lucerna' is a tall cane begonia grown as an indoor specimen. Its bamboo-like canes and large spotted leaves are favoured by mealybugs sheltering along stem nodes. Spider mites attack during dry winter heating periods. Regular wiping of the distinctive silver-spotted leaves helps with early detection.

White waxy colonies at cane nodes and leaf axils; honeydew and sooty mold on large leaves Dab colonies with 70% isopropyl alcohol; spray entire cane and undersides with neem oil; repeat weekly

Tiny pale spots and stippling across spotted leaves; webbing at leaf undersides in low-humidity months Mist foliage, raise indoor humidity, apply insecticidal soap or neem oil on a 7-day schedule

Clusters of soft-bodied insects on new growth and flower buds; curled tender shoots Pinch off heavily infested shoots; spray with insecticidal soap or a diluted neem oil solution
