One afternoon, as I sat on the front steps, I watched a string of ants scurry across my path in a crack of the sidewalk. These were big black ants and they literally moved in tandem, one after another. For some strange reason, they would all occasionally stop, rise up on their various back legs and fidget about in some jittery, arm-flailing motion, before assuming their marching stance and moving quickly on. I squinted, trying to fasten my sight squarely on each ant, because, in my imagination, I wondered . . . Is there a chance that each of those diminutive hymenopterous insects has a tiny I-pod dangling from his neck!?!?! Just a thought.
