4-5 inch worm/caterpillar
September 10, 2009
This was found in my sisters yard and we were just wondering what it was. We have never seen anything like this around here before. dont know how well the pictures will come out but its green with what looks like some reddish brown triangle shapes all along its back. it has very tiny spikes on its head and what looks like a hook that is very hard on the opposite end of it. its about 4-5 inches long and about the thickness of a cigar. when it was picked up with a plastic spoon it tried to stab the spoon with the “hook”. so maybe a little aggressive.
This is a Sphinx Moth Caterpillar, known as a Hornworm. It is most likely a Waved Sphinx, Ceratomia undulosa. The green caterpillar, according to Bill Oehlke, takes on a rosy hue prior to pupation.
