But experts worry about the ever-shrinking space for these very important life forms in the march of urbanization. B C Choudhury , former professor at Wildlife Institute of India (WII) and wildlife scientist, said that we have the tendency to put cement and stone at every possible opportunity , preventing on-ground vegetation growth.
“A major portion of rainwater now goes down the drain instead of accumulating in ponds or water bodies which provided breeding grounds for amphibians, reptiles and insects. Unfortunately, wherever there are such bodies, we are polluting them with insecticides and pesticides. Due to this, tadpoles (the intermediate stage of amphibian lifecycle) fail to grow into frogs,” said Choudhury.
Entomologists Vandana Thakur of Serenity Library says, “Monsoon provides insects the perfect temperature and humidity to thrive.Some butterflies and moths prefer to remain in pupa or at the frozen larva stage the entire winter, and come out during favourable weather like monsoon, and complete their life cycle.”
“Along with harmful insects, we are also killing dragonflies and damselflies that naturally keep insect population in check. Mobile radiation is also playing its part in damaging life forms,“ said Ramjee Nagarajan, programme coordinator, CEE.
