False colour scanning electron micrograph of an insectivorous plant, a Cape sundew, Drosera capensis, showing a leg of the 'psilid' fly (family Psilidae) held by a sticky secretion of the plant. ^ The sundew ensares its prey by means of tentacles capped by globular sticky glands, which simultaneously attract & hold fast the insect. Subsequent struggle stimulates the tentacles, which slowly move in, entangling the insect. Enzymes are secreted to digest the insect. This mechanism has evolved to supplement the diet of the sundew, growing in mineral deficient environments such as uplands & bogs. Nitrogen in particular is obtained. Mag: X29 at 35mm size.
