What's eating my alocasia infernalis?

Alocasia infernalis, with its near-black metallic leaves, is an uncommon collector's houseplant susceptible to the same indoor aroid pests as its relatives. Spider mites are the biggest risk in dry indoor air, while mealybugs hide in petiole joints. Thrips scar the distinctive dark foliage irreversibly, so early action matters.

Pale stippling on the dark leaf surface makes damage especially visible; fine webs on undersides Increase ambient humidity to 60%+, wipe leaves with a damp cloth, and treat with neem oil or insecticidal soap every 7 days.

White waxy tufts in petiole bases and leaf joints; leaves yellow and droop Apply isopropyl alcohol with a cotton swab directly to colonies, then spray with neem oil solution weekly.

Silvery or bronze streaks on new leaves; distorted unfurling growth; tiny pale insects visible Remove affected leaves, isolate immediately, and apply spinosad spray every 5–7 days for at least three treatments.
