Abstract

Every biological system contrives itself to evolve for its very survival. Evolution, is the finest machinery that refine biosystems that in turn is eventuated by the most ingenious engineer - The Nature. Utricularia striatula is an insectivorous plant categorized under a well celebrated bladderwort family. U. striatula varies from other Utricularia species; of being terrestrial and sometimes even epiphytic. In tropics, it grows conspicuously and diversely in Western Ghats specifically in coastal belt of Karnataka and Kerala, India, during the peak monsoon season (July-August) when the humidity is more than 90%. In aquatic bladderworts, the trap for insects work by rapid pressure detecting bio appliance; that bank on an ultra-fast passive suction bio device. This ultra-fast bio apparatus has always been a fascination for bioengineers. Being terrestrial, the classical under water mechanism of Utricularia species will not be expedient in U. striatula. Hence the deception for insects has to transform to operate under moist or even open-to-air environments. The objective of the study is to comprehend the insect deception machinery and its spatial modifications. Ultra structural studies using a scanning electron microscope revealed some interesting clues on spatial revisions of these fly trapping bio devices. The survival and adaptability of Utricularia is exclusively reliant on the fly entrapment bio device alterations.
