Tersa Sphinx Caterpillar

Western Tiger Swallowtail catepillar
October 27, 2009
I was wondering why the leaves of my penta plant were disappearing. Then this morning I found these “eyes” staring at me. At first I thought it was a plastic toy! What an amazing critter.

Tersa Sphinx Caterpillar

Hi Marabelle
Though it resembles a Western Tiger Swallowtail Caterpillar, your critter is a Tersa Sphinx Caterpillar.  The Swallowtail has one set of eyespots, while the Tersa Sphinx has numerous eyespots.  The Tiger Swallowtail Caterpillar does not have a caudal horn, and the Tersa Sphinx does possess a caudal horn.  Sphinx Moth caterpillars are often called Hornworms.  Penta is a typical food plant for the Tersa Sphinx Caterpillar.

Oleander Hawkmoth Caterpillar

Hi Doug,
It doesn’t appear to be feeding on oleander, but it looks like an Oleander Hawkmoth Caterpillar.  According to Bill Oehlke’s website, in addition to oleander, the caterpillar is also known to feed on “Minor hostplants are Vinca, Vitis, Gardenia, Asclepias, Jasminum, Trachelospermum, Amsonia, Carissa, Tabernaemontana, Mangifera, Rhazya, Adenium, Catharanthus, Ipomoea and Thevetia. Larvae will also feed on Ligustrum ovalifolium in captivity.

Banded Sphinx Caterpillar

Hi Frankie,
The Banded Sphinx, Eumorpha fasciatus, is one of several Sphinx Moths with highly variable caterpillars.  Though the darker colorful caterpillar is a version well represented in our archives, we believe the lighter morph is a new color variation that is not represented in our archives.  Bill Oehlke’s excellent website illustrates both of these color variations as well as several others.  The Banded Sphinx Caterpillars are known to feed on “primrose-willow, Ludwigia (water primrose) and other plants in the evening primrose family (Onagraceae). Grapes also serve as larval hosts.”

Death's Head Hawkmoth Caterpillar

Dear A. Livingston,
This is the caterpillar of a Death’s Head Hawkmoth, Acherontia atropos, and other than eating some leaves, it is not harmful to the plant it is feeding upon.  You may find additional information on the Sphingidae of the Palaearctic website.

Pandora Sphinx Caterpillar

Catapillar or worm?
October 4, 2009
This was found in southern Wisconsin on a grape vine. It is soft to the touch, even though the spotted outside looks like a “shell” When it stretches, it extends out of the “shell” Very different from anything we have ever seen before

Barbary Spurge Hawkmoth Caterpillar

Caterpillar (red, black, white, yellow)
September 28, 2009
Can you please identify this caterpillar? It was photographed near Lake Tizlit in the High Atlas Mountains of central Morocco. The nearest village is Imilchil where my daughter works as a Peace Corps volunteer. This is in “her” national park. The photo was made in later June in semi-arid conditions. It is perhaps 10 cm long.

Barbary Spurge Hawkmoth Caterpillar

Hi Tom,
This caterpillar reminded us of the caterpillars of the Sphinx Moths in the genus Hyles, so we searched Hyles and Morocco, and quickly arrived at a page for the Barbary Spurge Hawkmoth, Hyles tithymali mauretanica.  Your caterpillar looks very similar to the ones pictured in the photo on that page, but with slight color differences.  The website also has this note:  “(Taxonomic note. de Freina (1994) placed mauretanica as a subspecies of H. euphorbiae on the basis of minor morphological and behavioural differences, overlooking the many more characteristics that mauretanica has in common with tithymali.)
”   Upon following the link to Hyles euphorbiae, the Leafy Spurge Hawkmoth, the new page has photos of numerous color variations of the larvae which are called polymorphic.

Hi Daniel,
I am dazzled by your speed and research. From the description of the habitat (desert/steppe) and range (Atlas Mountains of Algeria and Morocco), this much be the one. I note (as you did) the slight variation in coloring (red line for yellow line, etc.) but it must be a cousin. Thanks much for offering such a service online. I posted the picture on Flickr and gave you credit for the identification:

One Eyed Sphinx Caterpillar

Dear S Logan,
What a nice find.  This is a One Eyed Sphinx or Cerisy’s Sphinx Caterpillar, Smerinthus cerisyi.  Bill Oehlke’s Sphingidae of the United States website has images of the adult moth as well as other stages of development.  This is a wide ranging species in North America.  In addition to willow, the larvae also feed on poplar.

Rustic Sphinx Caterpillar

Hi Tom,
Your photo is quite wonderful and it illustrates this Sphinx Caterpillar in its classic pose that resulted in the name sphinx.  We disagree with your identification.  We believe this is a Rustic Sphinx Caterpillar, Manduca rustica.  The best method for identifying both Sphinx Caterpillars and the adult moths, we believe, is to scan the images on Bill Oehlke’s Sphingidae of the Americas website.  The site has the option of viewing by individual states, so you are able to just search for species found in Texas.  Using that method, we identified your Rustic Sphinx Caterpillar on Bill’s website.
