It seems as though all of a sudden my butterwart has started to turn brown and dry around every dead gnat. The new growth is green and lush. But the leaves that are hosting dead gnat carcass are turning brown around the dead bugs, as if they killed the leaf that they died on. I am confused. Is this how the plant lives putting out more growth every time a bug kills the old leaf or should the leaf eat the bug and stay green. The butterwart ate gnats before and it never seemed to do this in the past. Should I cut these leaves off to focus energy on new growth or will the leaves revive themselves.
