What's eating my anthurium 'ace of spades'?

Anthurium 'Ace of Spades' is a prized collector houseplant most commonly troubled by spider mites and mealybugs. The large velvety dark leaves show stippling and sooty mold very clearly. Scale insects can colonize the thick stems. Because this cultivar is expensive and slow-growing, inspect every leaf weekly and act at the first sign.

Fine pale stippling dulls the velvety dark leaf surface; webbing appears on undersides in low-humidity conditions Wipe leaves with a damp cloth, raise humidity above 60%, and spray with insecticidal soap or neem oil weekly for 3 weeks

White waxy masses in leaf axils, along petioles, and in the crown; leaves yellow and new growth is stunted Treat each colony with isopropyl alcohol on a cotton swab, then apply neem oil spray covering the entire plant; repeat weekly

Hard brown or soft waxy bumps on stems and petioles; honeydew causes sticky leaves and eventual sooty mold Scrape off manually with a soft brush, then apply horticultural oil; systemic insecticide for severe infestations
