The bizarre yet beautiful carnivorous 'fanged pitcher plant' (Nepenthes Bicalcarata) - native to forests in Borneo - is a lethal operator. A foe to those insects who fly too close, lured in by the sweet smell of a delicious nectar. Deep reds, sap greens and unusual patterns make for an interesting species.
Insects who do fall inside the tubular pitcher will rarely escape. They will drown inside the pitcher in a liquid of the plants own making, where they are then broken down by digestive enzymes into nutrients that become available for use by the plant. A means of survival.
I also think they share a marked similarity to the praying mantas? The lips around the rim of the pitcher appear like forearms, praying for an insect to pass by. Killers of the forest, praying for food. Is seems wrong to fascinate over such a deadly plant, doesn't it? I will stop there.
