The future adaption of beetle

I predict that in the future the climate in the rainforest with be so humid and hot that the evaporation of the water will cause more and larger floods that will erode the food supply of the beetle at the ground level which will change the way they eat, live, and even look. The adaptions I predict are bigger wings for flying higher in the canopy, changing their camouflage, and for the beetles that are carnivores, they may even have to change their meat base diet to plant based diets.
