Spotted this big guy by the lake on our evening walk tonight. I’m interested to see what this caterpillar becomes!

Dear Liz,
We are surmising that there is a catalpa tree or cigar tree nearby as that is the food plant for the Catalpa Sphinx caterpillar you found. We have no images on our site of the adult Catalpa Sphinx, but you can see images on Sphingidae of the Americas.
