Your caterpillar is a white-lined sphinx moth larvae. The caterpillar colors can vary a lot…some have more green, some more black coloration, some have stripes, but the white dots you see on this one are on all variations. Caterpillars of this moth do vary greatly in color, but like most sphinx caterpillars they have a ‘horn’ or tail on the rear end.
These caterpillars feed on a wide variety of plants including spurge, plants in the evening primrose family as well as the rose family. They are not a pest, just a colorful cool insect.
The moths are commonly seen at dusk feeding on nectar of petunias or other flowers with tubes. They resemble hummingbirds and are sometimes called hummingbird moths.
There are 2 generations per year. These are found all over North America.
This caterpillar will not bite nor sting.
