What's eating my alocasia portora?

Alocasia Portora, a large upright tropical, is most commonly attacked by spider mites in warm, dry conditions. Mealybugs and thrips also target the broad leaves. Keep humidity above 50%, wipe leaves regularly, and isolate new plants before introducing them to your collection to prevent infestations.

Tiny yellow stippling on upper leaf surface; fine webbing visible on undersides in heavy infestations Increase humidity, shower the plant to dislodge mites, spray with insecticidal soap or neem oil every 5–7 days

Fluffy white residue at stem joints and leaf bases; leaves curl and yellow as insects feed Remove with alcohol-dipped cotton swab; treat remaining plant with diluted neem oil solution

Silver or bronze streaks and scarring on leaf surfaces; black frass dots visible on undersides Spray with insecticidal soap or spinosad-based spray; repeat every 5 days for three weeks
