What's eating my hemigraphis alternata?

Hemigraphis alternata (red ivy or waffle plant) is a trailing tropical grown for its metallic purple-green foliage. Spider mites are the biggest threat in warm, dry air, causing the distinctive leaf texture to look bleached. Mealybugs shelter in the dense trailing stems. Fungus gnats breed in moist soil. Keep humidity high.

Fine pale stippling bleaches the metallic leaf colour; webbing on undersides; plant looks dusty and declines rapidly Raise humidity; rinse the dense foliage thoroughly; apply neem oil or insecticidal soap spray every 5–7 days for 3–4 rounds

White waxy masses hidden in stem joints along trailing stems; yellowing leaves and sticky honeydew Work through each stem and dab colonies with isopropyl alcohol; follow with insecticidal soap spray; repeat weekly

Larvae feed on fine roots in moist soil; adults hover around the soil surface and can spread to nearby plants Allow the top inch of soil to dry between waterings; use yellow sticky traps; apply a Bti-based soil drench to eliminate larvae
