Laurel Sphinx moth larva

Sphinx kalmiae


Caterpillars feed on Apple (Malus), sweetfern (Myrica), Carolina rose (Rosa carolina), blueberry and huckleberry (Vaccinium), white spruce (Picea glauca), American larch (Larix laricina), and alder (Alnus). Caterpillars pupate in burrows in soft soil.


Me and my son found two of these while on an adventure walk yesterday out in our back 40. We now have 9 different larvae species we are observing. I find it very exciting.

Hi Sclark73! We've been informed that this is not Sphinx poecila, but Sphinx kalmiae. This is shown by the caterpillar's posterior "horn", which is blue with tiny black spines and can be seen in your third image. I will change the ID for you and add a reference.

Thank you tibiprada and Nina you are right they do. You would think the moth form would be just as vibrant but nope.

Sclark, I can see all three photos. The sphinx moths have the coolest looking caterpillars, don't they?
