Pest identification
What's eating my veined begonia (venosa)?
Spider mites
Signs: Pale stippling under the white felt coating on leaves; webbing visible at margins in very dry conditions
Control: Increase humidity cautiously (avoid wetting the felt), apply neem oil by wiping undersides; repeat every 7 days
Mealybugs
Signs: White waxy colonies blend into the felted white leaf surface — look carefully at stem bases and leaf undersides
Control: Dab with alcohol on a cotton swab; avoid saturating the felt surface; treat stems with neem oil spray
Fungus gnats
Signs: Larvae in overly moist soil damage the sparse root system; adults are a sign of overwatering for this succulent-type begonia
Control: Water sparingly and only when mix is dry; apply Bti drench and use yellow sticky traps for adults

What is eating my veined begonia (venosa)?
Begonia venosa is a distinctive Brazilian species with thick, white-felted leaves, grown as a houseplant. Its succulent-like texture makes it more drought-tolerant than most begonias but also means overwatering leads to root rot rather than pest pressure. Spider mites and mealybugs are still the primary pest risks in warm, dry interiors.
