I give an "Insect's-view" of the trapping mechanism of the Cobra Lily for those who wonder how this plant catches prey.

Ok, so some peeps can't understand Newfoundland vernacular so I have to write out the mechanism.

The whole leaf has nectar glands that are highly concentrated on the two leaf-like pieces hanging down and along the edge of the tube. They both go up towards that opening where the insect will follow. Looking up into the hole it is very bright with the sunlight. When the insect enters the opening, the light encourages it to go upward. Once realizing it is in a trap, it will either run around the inside wall and slip down into the tube or fly towards the light, bump into the "windows" and then fall. Inside the tube are covered in fine needle-like hairs that feel like silk in one direction but stop movement upwards. The deeper the victim goes, the tighter the tube until bottom is reached and the prey can't move any further in either direction. The walls sweat and drown the insect. Bacteria and mites assist the digestion.
