Inchworm goes a-loopin'

video

This larva of a geometrid moth was in my backyard last Sunday. Prior to watching this video (and 2 others I took of it), I had never paid close attention to the mechanics of their looping. One characteristic that struck me right away was that, unlike the front end, the back end is never lifted off the surface; it seems that it is simply dragged forward without losing contact with the substrate. The next time I see one of these I will try to get close-up shots.

I hadn't noticed that before, but it makes sense.

Good movie. Another interesting one: Go West!

It's as if a stick man is performing on stage...
