I left the back door open & this little guy wandered into my house . I’m just wondering what it is . I’ve never seen anything like it before. Its green with some light reddish, orangeish or brownish color all along its back. it has 1 very tiny tail . its about 3 – 3 1/2 inches long and a little thicker then a cigarette .

Dear Suni,
There is not much critical detail in your image, so we cannot be certain of the species, but this is a Hornworm in the family Sphingidae.  We believe it is most likely the Caterpillar of a Waved Sphinx,
Ceratomia undulosa, and according to the Sphingidae of the Americas site:  “Just prior to pupation, larvae frequently take on a rosy hue.”  According to BugGuide:  “Larvae feed preferentially on leaves of ash (Fraxinus spp.), especially Green Ash (F. pennsylvanica) in Canada, but also feed on fringetree (Chionanthus spp.), hawthorn (Crataegus), lilac (Syringa), oak (Quercus), privet (Ligustrum), and other woody plants.”  Do any of those plants grow near where you made this sighting?
