The kids (Aspen and Cedar) had found this caterpillar and we saw it start on its cocoon. I figured it would be a good chance to try out the time lapse on my new Nikon D800 for the first time. The first video was too short so it stopped long before I checked. I therefore started a new one. This cut merges the two and slows them down a bit over the two parts previously posted separately. The variation in lighting is because it was under natural light over several hours.
