What's eating my goeppertia roseopicta illustris?

Goeppertia 'Illustris' is most vulnerable to spider mites when indoor humidity drops. Mealybugs and fungus gnats also commonly attack this Calathea-relative. Its delicate painted leaves show damage quickly — maintain 50%+ humidity and inspect new growth weekly to catch infestations before they spread across the whole plant.

Pale stippling and loss of the distinctive leaf patterning; fine webbing on undersides; leaves curl and brown at edges Mist foliage regularly, wipe leaves with a damp cloth, and apply diluted neem oil or insecticidal soap spray weekly

White waxy clusters at leaf bases and stem joints; honeydew deposits; affected leaves yellow and distort Spot-treat with rubbing alcohol on a cotton swab, then follow with repeated neem oil applications every 7 days

Adult gnats hovering around soil; larvae chew fine roots causing wilting and stunted growth despite adequate watering Allow the top 2 inches of soil to dry between waterings; use yellow sticky traps; apply Bacillus thuringiensis israelensis (Bti) drench
