The Picher of Death
You may have heard of a plant called the Picher of Death. As you can probably tell by its name, it kills and eats insects. If you want to know how, read on!
To catch flies and other insects, this plant needs a bait and a trap. The bait in this case in nectar. The trap is the cup or ‘pitcher’ shaped leaves which have short hairs at the top to give the insect a sure foothold, but slippery hairs pointing downwards, so it can’t escape once it falls in. the other part of the trap is a digestive fluid inside the cup.
How it catches the insect is really quite simple. First the insect is attracted by the nectar. Then it slips on the smooth inner surface of the plant. Next it is forced downwards by the slippery hairs. Then it falls into the digestive fluid and is drowned.
An interesting fact about this plant is that the pitcher leaves can grow to the size of a fully grown adult’s hand.
