What's eating my large-flowered butterwort?

Large-flowered Butterwort (Pinguicula grandiflora) is a European carnivorous houseplant and rock garden plant with sticky leaves that catch small insects naturally. It is rarely pestered indoors. Aphids can colonize flower scapes in spring, and fungus gnats breed in wet media. Keeping conditions cool, moist, and well-lit largely prevents any meaningful pest pressure.

Green or black aphids cluster on flower scapes and new leaves in spring, distorting blooms Remove by hand or rinse with cool water; the sticky leaves trap small aphids before populations build

Larvae in wet acidic or organic media feed on roots and cause wilting in potted specimens Use a free-draining mix of limestone grit and peat; tray water lightly; use yellow sticky traps

Rasp irregular holes in leaves and may destroy entire rosettes when grown in outdoor rock garden or cold frame settings Hand-pick at night; use copper tape around pots; iron phosphate pellets (wildlife-safe) around outdoor plantings
