I found this today around a stump, while mowing the grass! I’ve never seen such a thing! People were telling me it sounds like a tomato or a tobacco worm, but it has no stripes like a tomato worm and has spots. What do you think?

Tersa Sphinx Caterpillar

Hi Kaitlyn,
The Tomato and Tobacco Hornworms are in the same family as this Tersa Sphinx Caterpillar, so there are certain similarities.  You have mentioned the differences that can be used to differentiate the Tersa Sphinx Caterpillar from other caterpillars in the family Sphingidae.  Perhaps you have penta growing nearby as that is a preferred food of the Tersa Sphinx Caterpillar.  See Sphingidae of the Americas for additional information on the Tersa Sphinx.
