What's eating my utricularia longifolia?

Utricularia longifolia is a large-leaved terrestrial bladderwort from Brazil, typically grown indoors in humid conditions. Its constantly wet, peaty substrate is ideal for fungus gnat breeding. Mealybugs occasionally colonize the fleshy stolons. Because this species is grown in very wet media, root rot from overwatering compounds pest damage quickly.

Larvae feed on stolons and fine roots; visible decline in plant vigour; adults hover persistently Bti drench applied every 2 weeks during warm months; minimize peat content in the substrate; yellow sticky traps

White waxy fluff along stolons at or just below the substrate surface; wilting and yellowing Remove and inspect stolons; treat with dilute isopropyl alcohol or insecticidal soap; repot into clean medium

Soft colonies on emerging flower stems; stunted blooms and sticky residue Knock off with water spray; targeted insecticidal soap on flower stalks only
