Stumble upon Sunday. This reminded me of a fascinatingly morbid BBC (earth?) series. A fungus that takes over control of an insect brain, directs it towards an area optimally humid for fungal growth, lets the zombified critter bite down into a leaf to anchor it in place, then finally kills and devours it. How on earth does this work? How does something like this evolve? In any case: it makes for great pictures, as Alex Wild shows.
