Round-leaved Sundew (Drosera rotundifolia) plants. This insectivorous plant traps its victims by means of tentacles capped by sticky glands, which attract and capture the insect as it forages for food. Any subsequent struggle stimulates the tentacles, which further entangles the insect. Enzymes are then secreted that digest the insect. This mechanism has evolved to supplement the diet of the Sundew, which grows in mineral deficient environments such as uplands and bogs. Nitrogen in particular is obtained from the insect. Photographed in Kinloch Hourn, West Highlands, Scotland.
