Cape Lappet Moth Caterpillar

Dear Claire,
Though most individuals have orange hair, we have found several examples on the internet of white haired Cape Lappet Moth Caterpillars from South Africa.  There are images of white haired individuals on FireFly Africa as well as on iSpot Nature.

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!
Cheers,
Adam

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.

Hi! I was trying to identify this caterpillar and the closest thing I’ve been able to find so far is a rosy maple moth caterpillar. The structure of the caterpillar in question looks right but the color doesn’t quite match what I’m finding online. How much color variation is there in a caterpillar species? Thanks in advance for your attention. I love you guys!

Pink Striped Oakworm

Dear Jenn,
Your caterpillar looks similar to the caterpillar of the Rosy Maple Moth, which is pictured on BugGuide, however, your individual is a different species in the same Royal Moth subfamily Ceratocampinae.  Your individual is a Pink Striped Oakworm,
Anisota virginiensis, a species with three distinct subspecies, that is pictured on BugGuide.

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

Subject:  Butterfly eggs?
Geographic location of the bug:  Los Angeles, CA on side of wood door
Date: 11/05/2017

Hello, I noticed a gray moth about 1 inch big sitting on the side of my door outside.  Then, I noticed that it seemed like the gray parts were falling off and then an orange yellow butterfly was underneath. The next day, the butterfly was gone, but there were tiny dark silver eggs in a triangle shape. I thought it was just a remnant, but then 2 days later, these tiny little bugs started growing out of the eggs, and now the eggs are all gone. I’m just wondering what kind of bug they are and why the butterfly laid it on the door instead of a leaf.  Will they all die and should I do anything? Thank you.

Painted Tiger Moth Caterpillar Hatchlings

Dear Lecia,
Based on your location, your description of the “gray moth” and the “orange yellow butterfly [that] was underneath” and the images of these newly hatched caterpillars, we are quite confident that the eggs were laid by a Painted Tiger Moth.  As an aside, a clutch of similar eggs hatched on our office screen door this week.  The Painted Tiger Moth is a pretty gray moth with reddish orange to yellow underwings.  Painted Tiger Moths are attracted to porch lights, and they frequently mate and lay eggs on the walls of homes that have lights that attract them.  Painting Tiger Moth caterpillar hatchlings look exactly like your images.  Painted Tiger Moths do not feed as adults and the female will die shortly after laying eggs.  It is possible the individual on your wall died and began to fall apart, first losing the wings which is why you thought the “gray moth” had a “orange yellow butterfly … underneath.”  Painted Tiger Moth caterpillars are generalist feeders that will eat a wide variety of weeds and other low growing plants in the yard.  For their first meal, they eat their egg shell and that provides them with the necessary energy to disperse in search of food.  It will save them a trip if you relocate them to a part of your yard with tender green sprouts, but they will also fend for themselves, though we imagine many will not survive.

Thank you so much.  I believe that you are right. Their eggs are completely gone now.
I really appreciate it. I Will try to move them to some leaves.

Sincerely,
Lecia Harmer
