Hornworm: Possibly Eumorpha species

Dear Adam,
This is an early instar Hornworm from the family Sphingidae, and it looks to us like it might be in the genus
Eumorpha, a group that has many members that shed the caudal horn in later, more mature instars, leaving a caudal bump instead of a horn.  We could not locate any images on Sphingidae of the Americas that looks similar, but often very young, recently hatched instars are not well represented in images.  This BugGuide image of a Gaudy Sphinx Caterpillar, second instar, is the closest visual match we could locate.

Awesome! That at least gives us a direction to go off of!

Is this a privet hawk moth caterpillar?  We found this on our cement patio November 9, 2017. It was around 6:00pm. We placed it in the dirt. Found it dead the next morning where we left it.

Rustic Sphinx Caterpillar

Dear Jill,
In our opinion, this looks like a Rustic Sphinx Caterpillar, a common species in Arizona, and its pink coloration indicates it is pre-pupal.  It is possible that the dirt where you placed it was too hard for it to dig, and that it has begun metamorphosis without going underground.

What killed the Hornworm????

Dear Cris,
This is a Hornworm in the family Sphingidae, though it is a species that loses the caudal horn when molting, leaving a caudal bump at the tail end of the insect.  Furthermore, it is dead.  We are not certain if it is the victim of an internal parasite, or if it was preyed upon by a predator that sucks fluids from the body of its prey like a Predatory Stink Bug.  We believe we have identified the caterpillar as that of the Gaudy Sphinx Moth,
Eumorpha labruscae, based on images of the caterpillar posted to The Sphingidae of the Americas.  This is a caterpillar that is thought by many to mimic a snake to protect it from birds.  Sphingidae of the Americas notes:  “There is a striking resemblance to a snake’s head and eye, and a flattening of the thoracic segments when the head is not retracted.”  We received similar images from you and from Ken who wrote:  “A friend sent me these photos from somewhere in Guatemala, taken today.  Any idea?”  We are presuming you are the photographer, though we used the image provided by Ken as it was horizontal in format, an orientation we prefer on our site.

Thank you Daniel, for your detailed response, it was still moving but looked sick. I am studing spanish in guatemalia and it was at my school, will check its condition today. Thank you again

Tersa Sphinx Caterpillar

Dear MB,
While it contains eyespots similar to those of the Tiger Swallowtail Caterpillar, your individual is actually a Tersa Sphinx Caterpillar.  They are frequently found feeding on Pentas in the garden.

Thanks for the quick response, so does this caterpillar morph into a large brown moth?
Hi again Mark,
The adult Tersa Sphinx is a most brown, and very aerodynamic moth.

Death’s Head Hawkmoth Caterpillar

Dear C Paylor,
This is a Death’s Head Hawkmoth Caterpillar,
Acherontia atropos, a species that gets its common name because of the skull-like markings on the thorax of the adult Death’s Head Hawkmoth.  There are some nice images on the Natural History Museum of Crete website.

Thank you so much for your speedy response. It’s nice to know what creatures are living in your garden.

Hi, I found this in my garden, used your site to identify it being a tomato hornworm, and wanted to forward you the photos.  Have a great day!

Tobacco Hornworm

Dear Joe,
The average gardener probably doesn’t care that this is actually a Tobacco Hornworm,
Manduca sexta, since it looks so similar to a Tomato Hornworm and both species feed on the leaves and fruit of tomatoes and related plants in the garden.  According to BugGuide:  “Larva: large green body; dorsal “horn” (usually curved and orange, pink or red) on terminal abdominal segment; up to seven oblique whitish lateral lines, edged with black on upper borders.   The similar looking Tomato Hornworm, Manduca quinquemaculata, has eight v-shaped stripes and a straight blue-black horn. These caterpillars are often confused and misidentified.”
