The word caterpillar comes from the Old North French caterpilose literally meaning "shaggy cat." Meanwhile, a Swiss German name for the creeping critters is teufelskatz, meaning "devil's cat." If there were ever a reason to wonder why these names came about, one look at our photo of the day should clear things up immediately. What a wonderful example of a caterpillar seen in Ecuador and photographed by Andreas Kay ... this may be the shaggiest devil's cat yet!
