From Meghan Holmes on Treehugger:
Because the [Catalpa] worms are also native, they have ample natural predators, including various wasp and fly parasitoids. Worms from the catalpa tree have long been valued as fish bait, and some fishermen plant the trees just for this purpose. When fully grown, they’re around 2.5-3 inches long, and somewhat variable in color, though primarily either dark or pale with a black stripe or dots down the middle of the back.
I’ve never heard of a tree that’s only 3 inches long. Poor little guy.
