Prey is lured by the glistening droplets of mucilage on the tip of the tentacles. Insects are captured by becoming mired in the thick sticky mucilage on the leaf surface, where digestion and absorption also take place. The tentacles of Byblis do not move. As is the case in some other carnivorous plants, some insect species are, or at least appear to be, immune to these plants' digestive and trapping mechanisms and share in the plants' booty. One of these is the wingless caspid which is able to walk over the mucilage with impunity. This capability is observed but not understood.
