My cat, Mr. Waffles, found this guy crawling around the gravel driveway. It looked like it was trying to burrow into the ground but it was all rocky there and couldn’t. I rubbed a leaf against it and it jumped and curled up and started to pulsate a little bit, like a defense mechanism. After a few seconds it uncurled and started to crawl away.

Hornworm ready to pupate

Hornworm ready to pupate

Hi Stedge,
This Hornworm looks positively ripe, like a juicy piece of fruit, was the first thought in our mind when we saw your images.  This Hornworm in the family Sphingidae is getting ready to pupate, so it has turned from green to those warm, glowing colors.  We believe we have correctly identified your Hornworm as an Elm Sphinx,
Sphinx chersis, thanks to the Sphingidae of the Americas site.  We are going to write to Bill Oehlke to see if he can verify our identification.

It is Sphinx chersis. Can you put me in contact with photographer so I can
seek  permission to post and can also find county.
Thanks for thinking of me.
Bill

Hello Bugman, I spied this critter the other day – it was trying to dig a hole in the compacted dirt road. It was about 4 inches long and about the width of my little finger. I’m in Freeport, ME…southern Maine on the coast. The dirt road leads to a campground..there is also a farm — cattle, goats, chickens, turkeys….
I wish I had turned it over with a stick to see what the legs were like.
Thanks so much for your time!

Dear Annie,
We just finished posting another image from Idaho of a Gallium Sphinx Caterpillar or Bedstraw Hawkmoth Caterpillar,
Hyles gallii, and you may read more about it on the Sphingidae of the Americas website.  According to the Butterflies and Moths of North America, its range is “Newfoundland south through Maine to Pennsylvania; west to Alaska, Yukon Territory, and California. Also found in Eurasia.”

Hi, Stepped outside and almost stepped on this caterpillar? Since I have never seen this type before, just wondering what it could be. It is 3″ to 3.5″ long. It is Fall here with record high temps. Tomorrow we are headed downhill as far as temperatures and rain go. We are at about 5400 feet above sea level, just outside of Yellowstone.

Hi Bugman,
There was only one of these giant hornworm caterpillars on the now dying tomato plant. I was quite surprised by the row of “eyeballs” on either side of the beast. I imagine they are solely for camouflage. Or do they serve another purpose?

Spiracles of a Tobacco Hornworm

Spiracles of a Tobacco Hornworm

Dear Diane,
The organs to which you refer are known a spiracles, and they enable the Tobacco Hornworm,
Manduca sexta, to breathe.  Spiracles are not unique to the Tobacco Hornworm (see BugGuide).  We are unable to do additional research at this time as our search engine keeps crashing our server.
