Yellow Banded Day Sphinx

Dear df,
We researched your caterpillar on Bill Oehlke’s wonderful website and we are pretty certain that this is a Yellow Banded Day Sphinx Caterpillar, Proserpinus flavofasciata.  As its name implies, the adult moth is diurnal.  According to Bill’s website:  “The Yellow-banded day sphinx, Proserpinus flavofasciata (Wing span: 39 – 49 mm), flies in Alaska south through British Columbia to Washington, Oregon, Idaho, Wyoming, and Colorado, and from British Columbia east across southern Canada to Nova Scotia and Maine.“  The website also indicates:  “Larvae feed on willow weed (Epilobium) and possibly thimbleberry (Rubus parviflorus).  Mature larvae pupate and overwinter in burrows dug under stones and other solid objects. The penultimate instar is pale green with a pair of pale, dorsolateral lines running from the head to the base of the short caudal horn. The last instar is brown-black with numerous black dots; caudal horn replaced by a black button surrounded by a white band edged with black.“  The depth of field on your photograph is quite shallow, but the focus on the head and caudal button makes identification easy.  We are going to copy Bill on this response so he can add your sighting to the comprehensive data he is compiling.

Juanita Sphinx Caterpillar

Bullseye caterpillar?
July 23, 2009
Hi Lisa Anne and Daniel, even with this caterpillar’s distinctive markings I am unable to identify it. It was found on the grass stem (cannot say it was feeding) on a prickly pear/sagebrush steppe but near a riparian area.
You are my last, best hope for an i.d. and I have unbounded faith in you!
Thanks in advance.

Hi Dwaine,
We are thrilled to be able to return a favor since you always send us such awesome butterfly images that are already identified.  The markings on your caterpillar are absolutely gorgeous, much like the weaving of a Persian rug.  We quickly identified this Juanita Sphinx Caterpillar, Proserpinus juanita, on Bill Oehlke’s awesome website.  Most Sphinx Caterpillars are characterized by a caudal horn, giving them the name Hornworm, but this species loses its horn on the molt between the forth and fifth instar according to the images posted by Bill.  We are going to copy Bill Oehlke on this reply since your gorgeous caterpillar differs slightly in coloration from the example he has posted.  Bill is also compiling comprehensive data on species distribution.

Rustic Sphinx Caterpillar

Very Large Caterpillar

I found this caterpillar on a Vitex tree while pruning. I had thought perhaps it was a Poplar Hawk Moth or maybe a Luna Moth caterpillar but, am now unsure after looking at pictures of each.

Hi Brad,
Properly identifying Sphinx Caterpillars can be a challenge for us, and it often takes considerable research.  Thanks so much for supplying the name of the food plant.  We just did a web search of vitex and sphinx and quickly arrived at this Sphinx Caterpillar of Texas page by Bill Oehlke that had a photo of the Rustic Sphinx eating Vitex.

Coneheaded Caterpillar
Tue, Jul 7, 2009 at 6:25 AM
Hi there! I found this little caterpillar at Newport News Park in Newport News, Virginia on July 6, 2009… He must have fallen out of a tree as I found him on my shoulder… I’ve searched and searched for an ID on the internet but to no avail – the cone-shaped head seems to be unique as the majority I’ve looked at that come close to the rest of his appearance are round headed… I posted his pic on our newspaper’s website and now have a ton of folks wondering what he is – it was one of them that pointed me your way ;o) Any help you can provided would be greatly appreciated!!

Dear Anna,
We have spent well over a fruitless hour trying to identify your caterpillar.  Alas, we have given up and we hope one of our readers will have better luck than we have had.  Our best guess on this is that it is a butterfly caterpillar in the family Nymphalidae, possibly the Subfamily Satyrinae which includes the Wood Nymphs and Satyrs, or perhaps the subfamily Apaturinae, the Emperors.  Our second guess would be that it is some type of Skipper in the family Hesperidae.  Sadly, these families are not really well represented on the internet with regards to caterpillars.

Greetings Anna and Daniel,
While this caterpillar may resemble something in the Satyrinae or Apaturinae, it’s actually a young MOTH.  Please compare your photo to these images of larvae from those two butterfly subfamilies:

Let me send an e-mail to Dave Wagner at the University of Connecticut, who’s the leading authority on US moth caterpillars.
Best wishes,
Keith Wolfe

Update from Keith Wolfe:
Monday, July 13, 2009
Hi Anna,
According to Prof. Dave Wagner, and Ryan’s brief comment, this caterpillar will metamorphose into a Pine Sphinx moth (one of four species in the Lapara genus of the Sphingidae family).  The green and white striping is an effective camouflage apparently shared by a number of butterfly and moth larvae that feed on pine needles.
Best wishes,
Keith

Ed. Note:
We are linking to Bill Oehlke’s posting of a Northern Pine Sphinx, Lapara bombycoides.

Tuesday, July 14, 2009
Thank you so very much for your time, effort, and energy in searching out the identity of this little guy!!  Please also pass along my thanks to Keith Wolfe, Prof Dave Wagner, and Ryan who spent their time researching this too!  Y’all are just GREAT – I’m going to let our folks on the newspaper website know right this sec and will use the link to your page to share…
THANK YOU – THANK YOU – THANK YOU!!!!!!!!!!!!!!!!

White Lined Sphinx Caterpillar

huge caterpillar!!!
Wed, May 27, 2009 at 6:08 PM
today (may 27th) while trimming tall grass and brush for my neighbor, i came across the largest caterpillar i have ever seen in california! it seemed very out of place, on a dry sun baked hill with all the grass mostly brown and dead for the summer. i picked it up and moved it to the shade under an oak. it was very lucky i noticed the little guy before my trimmer got the best of it. it was bright green with two black stripes running the length of it, with black and light yellow spots running down the side. it had a large yellow spike connected to its backside. it was 3 to 4 inches long.

Whitelined Sphinx Caterpillar

Hi Brennan,
This is a White Lined Sphinx Caterpillar, Hyles lineata. a moth that ranges over most of North America but is most often associated with desert areas of the Southwest.  This species has periodic population explosions in the desert during lush years and the caterpillar can be found in great numbers.  Native Americans feasted on the caterpillars.  The Caterpillars pupate underground, and your specimen was probably searching for some soft dirt in which to burrow.  The adult moths are often attracted to lights.

Death’s Head Hawkmoth Caterpillar

Yellow caterpillar in South Africa
Mon, Apr 13, 2009 at 10:43 AM
Good day,
A week ago we encountered a big yellow caterpillar in our garden and we have never seen anything like it before. We spotted it walking quite fast across a slab of slate towards a flowerpot.
It is just over 90mm in length. We picked it up and placed it in the garden underneath a bush, where it climbed onto a thin twig (see photo’s – I held a South African R2 coin next to it) and stayed there for the night and following morning. Sometime during the day it disappeared not to be seen again. Could you please help us to identify this creature?
Many thanks

Death's Head Hawkmoth Caterpillar

Death's Head Hawkmoth Caterpillar

Hi Linda,
This is the Caterpillar of a Death’s Head Hawkmoth, Acherontia atropos.  The adult moth is pictured on the movie poster of the Academy Award winning Silence of the Lambs and played a role in the narrative of that film.  Regarding the d erivation of name , a ccording to the Biodiversity of South Africa website:  “The Death’s head hawk moth is so called because of the skull-like pattern on the thorax . As far as the latin name is concerned, according to Pinhey (1975) : ‘Atropos, one of the Fates, was a daughter of Nox and Erebus and was illustrated… with veiled face and a pair of scissors to cut the thread of life. This is the thoracic pattern of a mask with scissors below it. A sinister but undeserved portrait.’”  Excellent information and more photos can be found on the Sphingidae of the Western Palaearctic website.  The downward curve of the horn is distinctive in the mature caterpillar and is evident in one of your photographs.  By needs, we are presuming you want to raise the caterpillar to maturity.  Your photo of the yellow caterpillar indicates it is mature, or fifth instar and that it will soon pupate.  You should continue to feed the Death’s Head Hawkmoth Caterpillar with leaves of the plant on which it was found, and provide it with several inches of loose soil, not too moist and not too dry.  The caterpillar will dig into the dirt to pupate.  When its metamorphosis is nearly complete, the pupa will wriggle to the surface, the skin will split, and an adult moth or imago will emerge.

Death

Hi Siraaj,
At first we were going to write back and just say that you found a species of Hawkmoth Caterpillar in the family Sphingidae, commonly called Hornworms because of the caudal horn.  When we googled Sphingidae Africa, we quickly found an image of a Death’s Head Hawkmoth Caterpillar, Acherontia atropos, on a Biodiversity of South Africa website and we feel pretty confident that is your species.  The adult moth is pictured on the movie poster of the Academy Award winning Silence of the Lambs and played a role in the narrative of that film.  Regarding the derivation of name , according to the Biodiversity website:  “The Death’s head hawk moth is so called because of the skull-like pattern on the thorax . As far as the latin name is concerned, according to Pinhey (1975) : ‘Atropos, one of the Fates, was a daughter of Nox and Erebus and was illustrated… with veiled face and a pair of scissors to cut the thread of life.

Tersa Sphinx Caterpillars

Unknown caterpillars
Mon, Jan 5, 2009 at 4:20 AM
I thought I picked two brown caterpillars with fake eyes from my mother’s penta plant in Sun City Florida yesterday. When I opened the jar to photograph them this morning, I had two browns and two greens, all with false eyes. I never kill bugs without knowing what they are but I can’t find these in my caterpillar book.

Dear V,
Both the green caterpillars and the brown caterpillars are the same species.  The Tersa Sphinx, like many other Sphinx Moths, have caterpillars in different colors.  These different morphs probably aid in the survival of the species.  Predators that notice the brown caterpillars may not notice the green individuals just inches away.  To see images of the adult moth and to read more about the Tersa Sphinx, Xylophanes tersa, you can search Bill Oehlke’s excellent website.

Thank you so much! I gave the caterpillars to a friend with a lot of penta and a six-year-old grandaughter who loves bugs — she’ll take good care of them :)

Pandorus Sphinx Caterpillar parasitized by Braconid Wasp

Large Fuzzy Fat Catapillar with dangles
Mon, Nov 3, 2008 at 4:00 PM
Found this critter right outside my kitchen window, seemed to move very slowly over the week. Then started growing the dangling things off of his/her body.

Pandorus Sphinx Caterpillar parasitised by Brachonid Wasp

Pandorus Sphinx Caterpillar parasitised by Braconid Wasp

Hi M.,
This is a Pandorus Sphinx Caterpillar, Eumorpha pandorus, and it has been parasitized by a Braconid Wasp. The Brachonid Wasp lays its eggs inside the caterpillar and the larvae feed on the internal organs, eventually emerging and pupating on the outside of the caterpillar. You can see some of the pupae have “hatched” and the adult Braconid Wasps have emerged. Sadly, the Pandorus Sphinx Caterpillar will die.

Ello Sphinx Caterpillar and Emerged Adult

Large, smooth, green caterpillar in Florida
Hello Bugman!
I hope you can help me. I found this lovely, large caterpillar on a silver buttonwood bush in my Florida yard. I live in Brevard County on the east coast. Two sites have suggested that it may be a Tantalus Moth, but I could not find photos of a Tantalus Moth caterpillar online or in any books to verify it. This picture shows the critter on the branch he was eating. Do you recognize this caterpillar? He is 3″ long, the size of my index finger. Thank you!

Fig Sphinx Caterpillar

Fig Sphinx Caterpillar

Hi Donna,
We are nearly certain that this is the caterpillar of the Fig Sphinx, Pachylia ficus. This is a highly variable caterpillar. We have checked Bill Oehlke’s excellent website, and the coloration on your specimen somewhat resembles one on his site, but it is still different. We are going to copy Bill Oehlke on this response so he can verify that our identification is correct. If our identification is correct, then the silver buttonwood bush, Conocarpus erectus, would be a new host plant for the caterpillar which feeds on members of the genus Ficus, the figs. Bill Oehlke may also request permission to post your interesting color variation on his own website.

Thank you, so much, for following up with me. I have several silver buttonwoods, and I have poured over all of them looking for more caterpillars, but this guy seems to be it. One of our neighbors has a fig tree, which may be worth mentioning. I don’t know if it translated in the photos, but the darker shade on the caterpillar’s back is purplish. Quite lovely!
Again, thank you.
Donna Peters

Daniel,
Here is reply I sent to Donna regarding “Pachylia ficus”
I am going to ask Jim Tuttle for his opinion. I wil get back to you and to Donna if I get an id from Jim

Hi Donna,
I am pretty sure the larvae are of one of the Erinnyis species, probably Erinnyis ello, possibly Erinnyis alope. I wil try for a second opinion and get back to you.
I am almost positive they are not Pachylia ficus.
Bill Oehlke

Daniel,
Jim Tuttle has confirmed the larvae are Erinnyis ello.
Bill Oehlke

Update: 11 November 2008
Hi Bill,
The caterpillar you identified for me as Erinnyis ello emerged today and was released this evening. I have attached a photo. It vibrated it’s wings on the potted plant for about 5 minutes, then flew away over the house. My 7 year old son loved it. Thanks again! :)

Rustic Sphinx Caterpillar, not Incense Cedar Sphinx

LARGE Caterpillar
Thu, Oct 9, 2008 at 9:32 AM
I found this 8 inch long black caterpillar in my pool skimmer. It is the size of a cigar, has a green face and a green antennae poking up from it’s butt. And it stinks! We live in North Jeannine,
Phoenix, Arizona

Incense Cedar Sphinx Caterpillar

Incense Cedar Sphinx Caterpillar

Hi Jeannine,
Though we question the exact size of your caterpillar, we will agree that Sphinx Moth Caterpillars can get quite large. We suspect this may be an Incense Cedar Sphinx Caterpillar, Sphinx libocedrus . Except for the color of the horn, it seems to match the dark form of
the caterpillar on Bill Oehlke’s website. We are going to copy Bill Oehlke on our reply as he is compiling comprehensive data on species distribution. We also hope he will confirm our identification.

Daniel,
Thank you for keeping me in check. I was so impressed with it’s size and smell, that I was too excited to remember to take a pic with a ruler. So you are quite right, it is “only” about 5 1/2 inches long. I’ve attached the pic I took this AM with my tape measure. And if you could copy me on Bill’s response to your e-mail, I would greatly appreciate it.
Thanks for the info!
Jeannine

Daniel,
I think it is an unusual dark Manduca rustica. I am going to send it and another similar one I received couple weeks ago, also from Arizona, to Jim Tuttle. Will let you know.
Bill Oehlke

Thanks Daniel,
Don’t know if I emailed you but Jim Tuttle has confirmed the dark larva found in swimming pool in Arizona as Manduca rustica.

Blinded Sphinx Caterpillar

Sphinx Moth?
I saw this caterpillar on a blueberry bush in a meadow in Shenandoah. I know for sure that it is a sphinx moth caterpillar, but I’m having trouble pinpointing the species. I’ve looked through your website and guidebooks but with no luck. Since it was eating the blueberry leaves, I’m guessing that it might be a Huckleberry Sphinx?
Thank you! Your site has been a wonderful source for identifying all the bugs I come across. Shenandoah National Park, Virginia

Blinded Sphinx Caterpillar

Blinded Sphinx Caterpillar

Hi Holly,
Your caterpillar is a Blinded Sphinx Caterpillar, Paonias excaecata.  Many times this caterpillar is green, but BugGuide has examples of this mottled color variation.  Bill Oehlke’s very comprehensive Sphingidae site does not depict this color variation.  As he is currently compiling comprehensive data on species distribution, we are copying him on this reply.  He may also request permission to post your photo to his site.
