Guest guest Posted February 16, 2004 Report Share Posted February 16, 2004 The Power of Empathy by Arthur Ciaramicoli and Katherine Ketcham. " we find an unusual but definitely empathic relationship developing between ants and myrmecophilous (ant-loving) caterpillars. These caterpillars have 'ant organs' specifically designed to attract and communicate with ants. One of these organs is located on the caterpillar's posterior; when stroked by ants this gland secretes a clear fluid rich in amino acids. The ants lap it up, getting a healthy, nutritious snack for a minimum amount of effort. " With a free meal provided whenever they want it, the ants tend to stick around. That's precisely what the caterpillar wants, because in times of trouble you can't find a more loyal or tenacious friend than an ant. When the caterpillar is threatened by a predatory insect like a wasp, it enlist the ants' help by calling on a second 'ant organ.' A pair of tentacles behind the caterpillar's head emits a chemical signal, which alerts the ants to move into a defensive position, ready to attack any offending creature. If the wasp tires to sting the caterpillar, the ants are prepared to fight the enemy to death. " Ant-loving caterpillars provide a fascinating look at the precursors of negative' empathy. The caterpillar dupes the ants into thinking that their survival depends on the caterpillar's destiny when, in truth, the caterpillar needs the ants much more than the ants need the caterpillar. The wasp, after all, could care less about the tiny ants--it wants to feast on the plump, fleshy caterpillar. But the ants have been won over by the free twenty-four- hour buffet and the caterpillar's ability to communicate with them in a language they understand. With these enticements the ants align themselves with the caterpillar, willing to fight to the death to protect it. " I received this from a friend. I found it fascinating. I am disinclined to say the caterpillar *dupes* the ants however. It is Nature Herself that has created this arrangement. This reminds me of some recent reflections about ants of my own. I was getting some ants streaming into my bathroom. I used my usual technique of spraying Windex on their " trails " . It seems to work pretty well. My theory is that ants know where their trails are by way of " chemical markers " laid down. The idea with the Windex is to obliterate/diminish their ability to read those signs. Anyway, finding a stray ant here and there I would squash it with my fingers. I thought of the Jainists and others who might abhor such " killing " , but to me that is no different than trimming the leaves of a hedge. As I see it, it is not the " ant " that is the organism, but the colony. A single ant is to the colony as is a leaf to a bush. To explore that notion further, note that to kill the queen is to kill the colony. That would be analogous to destroying the brain or heart of an animal. You might say the queen is a " vital organ " of the colony. Note the " step up " in abstraction from ant to colony. It is a similar step up to move from colony/critter to species. In the case of the " Power of Empathy " article, the relationship is not really between ant and caterpillar, nor even between ant colony and caterpillar. Rather the relationship is between the ant species and the caterpillar species. And that is my point in saying the arrangement is created by Nature Herself.
