In 1996, when Microcmos came out, I was fascinated by the world of bugs. Underneath our feet (and leaves) exist tremendous activity of little creatures finding food, fighting, mating, warring, and struggling to maintain their existence. That's probably why I capture bugs in my home and let them go outside. I figure they have plenty to do in their spare time rather than racing up and down windows thinking there's a way through the glass when there's not.
I'm such a naturalist. I can't help it. Let the little critters be.
