Sphinx Larva - Ceratomia catalpae

Sphinx Larva - Ceratomia catalpae
Gettysburg, Adams County, Pennsylvania, USA
August 5, 2005
Does anyone know what species? Thanks!

Catalpa sphinx, I think
Ceratomia catalpae. See Caterpillars of Eastern Forests online. But it looks like it's on the wrong host plant! Maybe there's a similar species.

Thank You
Looks like you are right. As far as the host plant, I'll see if anyone else knows about it.

Sphinx Larva- Ceratomia catalpea
Date 8/06/08 found multiple catapillers on a Toby tree in Pittsburgh Pa.

I've never heard that name before
but after browsing the web a little, looks like Toby Tree is a local common name for Catalpa, which is the right host plant for this species.
