What's eating my codonanthe gracilis?

Codonanthe gracilis is a delicate trailing gesneriad kept indoors. Mealybugs target the soft stems and leaf axils most often. Spider mites appear in low-humidity environments, and fungus gnats can colonize moist potting mix. Maintaining moderate humidity and good air circulation is the best preventive strategy for this species.

Cottony white tufts at leaf joints and on stems; sticky secretions and stunted, yellowing foliage. Use an alcohol swab on visible colonies; follow with a neem oil spray every 7–10 days for a month.

Tiny yellow stippling on leaves; fine webbing under leaves and along thin stems; foliage drops in heavy infestations. Shower the plant to dislodge mites; apply neem oil or insecticidal soap; increase humidity around the plant.

Adults hover near soil; larvae damage fine roots in continuously moist mix, weakening the plant. Allow soil surface to dry between waterings; drench with Bacillus thuringiensis israelensis; use yellow sticky traps.
