A fly trapped on the leaf tentacles of the carnivorous plant, Drosera rotundifolia, the sundew. It is attracted to the plant by sticky droplets at the tips of the tentacles, which extend from the leaves. The tentacles are of two kinds; longer marginal ones & shorter inner ones. Prey sticks to the tips of the longer ones, which bend over bringing it inward towards the shorter ones. Proteolytic enzymes secreted by the tentacles digest the insect & the products are absorbed by the leaf. Drosera grows in a nitrogen deficient environment (bogs), which it overcomes through a carnivorous diet.
