Dried-up Worms on Patio Could be Euonymus Caterpillars

“My patio furniture and patio has several of these dried up worms and what looks like excrement everywhere”, states this reader concerning the dark green organism with black spots pictured below. “We have a pretty dense canopy of trees but I have never seen this before. Could you help me identify the worm and tell me if this is indeed worm excrement? Thank you.” Firstly, we think that the worms our reader has been finding are caterpillars: the organism’s bulbous head, prolegs, and coloration all point to this fact. That said, the coloration is a bit off: the blackish part of its body almost looks like it has been burnt, and the greener part at its rear suggests it used to be a much more vibrant green. Maybe this is a result of the caterpillar drying out as our reader suggested.
