This is an important distinction between this moth and other species. On the other hand, the hindwing features brownish-gray coloration with three darker lines crossing the wing source.
When observing the moth’s head, you’ll notice lateral stripes on both sides. Moreover, the moth’s body has a mix of red, green, black, and white hues, providing an interesting visual contrast. The caterpillars, which will eventually turn into adult moths, are known as hornworms due to the horn-like structure found on their body.
So, when you come across a Waved Sphinx Moth, pay attention to its unique physical characteristics such as the wavy lines on its wings, the white reniform spot, and the checkered fringe. This beautiful specimen is certainly a marvel of nature’s design.
The life cycle of the waved sphinx moth consists of four stages: egg, larva, pupa, and adult. Let’s dive into each stage briefly.
When a female waved sphinx moth lays her eggs, she carefully places them on the leaves of her host plants, which usually belong to the walnut or hickory tree family. The eggs are oval and small, waiting to hatch into hungry little caterpillars.
When the eggs hatch, caterpillars emerge and start feeding on the host plant. The larvae, also known as hornworms, have a distinctive horn-like structure at their tail end. Growing through five instars, these caterpillars change their colors and patterns, eventually reaching a length of about 3 to 4 inches.
When the larva is fully grown, it will leave the host plant and search for a suitable location to pupate. In this pupal stage, the caterpillar forms a protective cocoon around itself and starts its transformation into an adult moth. Some waved sphinx moth caterpillars may overwinter as pupae, waiting for favorable conditions in the spring.
Finally, the adult waved sphinx moth emerges from the pupal case. With a wingspan of about 3 to 4 inches, these moths are known for their beautiful patterns on their wings. As adults, the main goal is to find a mate and continue the life cycle. They feed on nectar from flowers, using their long proboscis to reach the sweet treat.
Now you know the essential stages of the waved sphinx moth life cycle. From eggs to adults, each stage is fascinating and vital for their survival.
The Waved Sphinx Moth (Ceratomia undulosa) can be found in a variety of habitats throughout North America. In the United States and Canada, these moths are known to inhabit regions with forests.
Now let’s explore the range and habitat preferences of the Waved Sphinx Moth in a bit more detail:
- Range: These moths are widespread in North America, ranging from southern Canada to the United States.
- Habitat Preferences: They are well adapted to forests in various regions, making them a common sight in wooded areas.
In their habitats, Waved Sphinx Moths play a crucial role as pollinators. As you explore these forests, keep an eye out for these fascinating creatures.

Dear Colorado Moth Lover,
We believe this is a Waved Sphinx, Ceratomia undulosa, based on photos and information posted to Bill Oehlke’s excellent website, however there are several other similar looking species found in Colorado. We are going to copy Bill Oehlke with our reply so that he can incorporate your sighting into the comprehensive database he oversees, and perhaps he will be able to confirm our identification.
Hugely helpful!! Thank you so much!!
Bill Oehlke Confirms Identification
Denver, Colorado Sphingidae is Ceratomia undulosa.
Letter 2 – Tobacco Sphinx and Waved Sphinx
Thanks for confirming my Cecropia silkmoth yesterday. It’s by far the most impressive moth I’d ever seen. Today, I have a couple of new ones (my wife Carol seems to have a knack for spotting unusual insects and bugs in her garden). Based on a photo from your site, I think the first is a tobacco sphinx moth. It’s about 3.5 inches from wingtip to wingtip as shown (I estimate 4 – 5 inches if fully extended). I believe that the second is also a variety of sphinx moth, but I wasn’t able to find a match on your site. As shown, it’s about 2 inches wingtip to wingtip (estimate 3 – 3.5 extended). The abdomen is a mottled gray above with no distinctive markings. The underside is a lighter gray with a series of dark spots of varying sizes along the midline. I was unable to get the moth to show me its hind wings without it fluttering around out of control. My family and I would appreciate an ID if you can. Many thanks, and a great site.

|Tobacco Sphinx||Waved Sphinx|
Hi again Larry,
You are absolutely correct on the Tobacco Sphinx or Tomato Hornworm, Manduca sexta. That is a Grapevine Beetle lurking in the background. Your second Sphinx we believe to be the Waved Sphinx, Ceratomia undulosa. We located it on this Moths of North America site. It feeds on ash, oak and hawthorn and other trees.
Thanks for your reply and the link to the super NPWRC site. I noted that their site doesn’t list any confirmed sightings in my county for any of the moths you helped me identify, so I’m forwarding my photos to them as well.
Letter 3 – Waved Sphinx

I saw this big moth clinging to a cedar tree in my yard last June. It was about 4 inches long.
This is a Waved Sphinx, Ceratomia undulosa. You may read about it on Bill Oehlke’s wonderful website.
Letter 4 – Waved Sphinxes in Pennsylvania
Sphinx Moths meet Hello Kitty
Location: Southeastern Pennsylvania
July 26, 2011 4:32 pm
Late the other night (7/21/2011), here in Southeastern Pennsylvania, I was delighted to find four Sphinx Moths flying around my floodlight. My question is: Are they Manduca sexta (Carolina Sphinx) or Manduca quinquemaculata (Five-spotted Hawkmoth)? I just can’t tell! I sure did enjoy getting up close and personal with them, though–it was hard getting them off of me! I think they like Hello Kitty! Thanks so much for your help!
Signature: Diane Cameron, insect enthusiast
Your confusion over the identity of these Sphinx Moths is understandable. They are actually very pale Waved Sphinxes, Ceratomia undulosa, and they are in the same tribe, Sphingini, as the Carolina Sphinx and the Five Spotted Hawkmoth. Our favorite way to identify Sphinx Moths is to begin with the Sphingidae of the United States website, and then go to the state listing for Pennsylvania, and then click through the possibilities until we find a match. That is where we found the Waved Sphinx which is part of the Sphingidae of the Americas website.
Letter 5 – Waved Sphinx from Canada
Subject: Is this beauty hawk moth and why do they shake their wings?
Location: Winnipeg, Manitoba, Canada
June 11, 2014 9:16 am
Hi guys. I’ve previously found a blinded sphinx hawk moth in the same area where just today I saw this unassuming beauty. It was sleeping? When I brushed up against it by accident with my lens, it fell into my hands, started walking on my arm,and then it’s wings shook like it was trying to fly, but couldn’t. Was it cold, and needing to warm up to flee the scene – or was it a warning? It looked in perfect health. I put it gently back on the wall, and it continued its wing shaking. Thank you kindly in advance.
Signature: Maggie M.
We believe we have correctly identified your Hawkmoth as a Waved Sphinx, Ceratomia undulosa, thanks to images posted to the Sphingidae of the Americas website. We have observed the behavior you describe, though we cannot provide a definitive answer regarding why moths flutter.
