Under what circumstances would a species of meat eating animals be most likely to evolve to eat plants

Any insect unlucky enough to land on the mouth-like leaves of an Australian pitcher plant will meet a grisly end. The plant's prey is drawn into a vessel-like ‘pitcher’ organ where a specialized cocktail of enzymes digests the victim.

Now, by studying the pitcher plant's genome—and comparing its insect-eating fluids to those of other carnivorous plants—researchers have found that meat-eating plants the world over have hit on the same deadly molecular recipe, even though they are separated by millions of years of evolution.
