"Stylidium" species with glandular trichomes on their sepals, leaves, flower parts, or scapes have been suggested to be protocarnivorous (or paracarnivorous). The tip of the trichome produces a sticky mucilage—a mixture of sugar polymers and water—that is capable of attracting and suffocating small insects. The ability to trap insects may be a defensive mechanism against damage to flower parts. However, trichomes of "S. fimbriatum" have been shown to produce digestive enzymes, specifically proteases, like other carnivorous plants. Adding species of "Stylidium" to the list of plants that engage in carnivory would significantly increase the total number of known carnivorous plants.
