Insidious and infectious some fungus spores invade the systems of insects and consume them from the inside out. Included in this gallery are images showing the result of a Cordyceps or Sac Fungus invasion on unlucky ants. Once infected the spores change the behavior of the animals making them move to higher ground and latch onto a leaf or twig to stabilize themselves. Over several weeks the paralyzed insect is consumed, the fungus emerges from the carcass and distributes its spores to infect additional hosts. If unchecked the infection can wipe out an entire ant colony!
