So far, the best-known attractants in carnivorous prey traps are nectar, colour and olfactory cues. Reporting a new prey capture mechanism in some species of carnivorous plants. They found the existence of distinct blue fluorescence emissions at the 'capture spots' of Nepenthes, Sarracenia, Drosera, Pinguicula, Dionaea muscipula and Utricularia stellaris at UV 366 nm. When the capture spot was masked by coating a non-fluorescent extract, the pray capture was drastically reduced. The study has been published as a short research paper in the current issue of 'Plant Biology'
