What's eating my goeppertia bella (calathea bella)?

Goeppertia bella (Calathea bella) is most susceptible to spider mites, which explode on the delicate patterned foliage when humidity drops. Mealybugs and thrips occasionally attack. Maintaining 60%+ humidity is the most effective prevention; treat any infestation promptly as Calatheas can decline quickly under pest stress.

Stippled, dull leaf surface with fine webbing; pattern markings become washed out Raise humidity, wipe leaves with a damp cloth, spray insecticidal soap or neem oil every 5 days for 3 rounds

White fluff in leaf sheaths and stem bases; sticky residue; leaves yellow and curl Dab with alcohol, drench soil with neem if root mealybugs suspected, repeat treatments every 10 days

Silver-brown streaks or patches on leaves; distorted new growth; tiny dark frass specks Remove heavily affected leaves, apply spinosad or neem oil spray, use blue sticky traps to monitor adults
