How a Cobra-Lily uses light traps
Enticement – The ‘fangs’ of the lily entice insects with fragrant nectar. Browsing on the sweet bait, victims wander closer to the trap … and then they’re inside.
False hope – Within a domed chamber, windows of light glow brightly. Confused and unable to find the real exit, the prey tries frantically to escape.
Leisurely feast – Exhausted, the victim stumbles and falls into the pitcher. It drowns in the pool of water at the base, and is devoured by larvae, slime mites and bacteria.
Parrot pitcher plant – amphibian hunter
The Parrot Pitcher-plant (Sarracenia psittacina) hunts crawling insects. Its pitchers lie on the ground, and when its boggy habitat is flooded, they become submerged.
Equally deadly underwater, the traps attract tadpoles that, once inside, can’t find the dark exit. Myriad sharp, spikey hairs point towards the trap’s end, and the tadpoles are forced to their doom.
