I was just wondering what these caterpillars are and if they’re toxic or not. We have thousands here on a large bush and when I noticed them one struck at me. And my 2 year old son plays around and under the bush and I need to know what I should do.. leave them be or remove the bush?
But still I would love to know what they are because they’re quite beautiful.

This is the caterpillar of a Catalpa Sphinx, Ceratomia catalpae. The excellent Sphingidae of the Americas website does not have any examples of caterpillars with markings like your individual, however, they do state: “Colouration of mature larvae is somewhat variable, and there appear to be two primary color phases, dark and pale. In the dark phase, there is a broad, solid black band down the back, bordered by white lines. The sides are yellowish with some black spots and vertical lines.” BugGuide does have a photo of a Catalpa Sphinx with your coloration. They are not toxic and they pose no threat.
