What's eating my sonerila margaritacea?

Sonerila margaritacea is typically grown in terrariums or high-humidity enclosures where its preferred moist environment deters spider mites. Fungus gnats are the most realistic pest, attracted by the consistently damp substrate. Mealybugs occasionally appear in leaf axils. Good ventilation prevents fungal problems that are more common than insect pests.

Larvae damage shallow roots in moist potting mix, causing wilting and yellowing; adult flies are a nuisance. Allow the top layer of substrate to dry slightly between waterings; apply Bacillus thuringiensis var. israelensis (Bti) drench or use sticky yellow traps.

White cottony wax in leaf axils and on petioles; sap feeding slows growth and causes leaf distortion. Remove with an alcohol-dipped swab; apply diluted neem oil or insecticidal soap spray for larger infestations.
