Appearance
''D. capillaris'' is a small plant, usually ranging from 2 to 4 cm in diameter, but in wet habitats it has been known to grow up to 7 cm. In strong sun the entire plant appears red with round, spoon-shaped leaf blades sporting numerous tentacles. In normal light, the leaves are lime-green and the tentacles red. The leaves are arranged in a rosette and generally lie flat on the ground.At the end of each tentacle is a mucilaginous secretory gland. This gland secretes droplets of fluid which gives the plant its glistening, dew-drop appearance. Insects, upon being attracted to the plant through the nectar-like appearance and odor of the secretions, become stuck to the mucilage.
With this stimulus, the tentacles begin to slowly enclose the victim. In a matter of minutes, the sundew begins to secrete digestive enzymes and acids that start to dissolve its victim's body. The glands then start to absorb the nutritious liquified insect. It has been found that these plants only respond to objects of nutritional value and not to sand, paper, or water.
