What's eating my utricularia subulata?

Utricularia subulata is a carnivorous bladderwort that largely resists pests — its trapping mechanism deters fungus gnats and small flies. Aphids and mealybugs occasionally attack above-ground tissue, and algae overgrowth can smother the tiny rosettes. Keep water trays clean and bright to minimise problems.

Clusters of tiny insects on emerging flower scapes; distorted or stunted growth Rinse with a fine mist of distilled or rainwater; avoid soap sprays that may harm carnivorous foliage

Larvae in wet substrate; adults hover around the growing medium The plant's own bladder traps catch many larvae; improve airflow and avoid standing water deeper than necessary

Green slime smothers the tiny rosettes, blocking light and air Reduce fertiliser (feed nothing), increase light, and change tray water frequently
