Sundews are sticky flypaper plants. They bear long tentacles on their leaves, and these stalks are tipped with glands which are often brightly colored. The glands exude attractive nectar, adhesive compounds, and digestive enzymes. Insects that land on the leaves stick fast and are digested. Often nearby glandular tentacles are stimulated and also adhere to the insect, and on many species the entire leaf coils around the prey. These motions are usually slow, taking minutes or hours to occur. An often overlooked aspect of tentacle motion is the fact that a tentacle can bend in just about any direction. But when a bug is caught on a leaf, all the tentacles know the direction to bend towards. That’s pretty cool, scientists wonder how it is done.
