Here in Panamá is common the encounters with worms if you live near forest zones. Here two species that I want to know more about. I think the fist one can be a hawkmoth caterpillar and the second one maybe a silkmoth caterpillar. Thanks in advance, bugman.

Possibly Automeris species

Possibly Automeris species

Dear KLS,
We agree with your identifications, but alas, we haven’t the time right now to investigate further.  Your images and the caterpillars are both wonderful.  We believe the Silkmoth Caterpillar may be in the genus
Automeris, or a closely related genus. Perhaps one of our readers can investigate this further.  We will also try to contact Bill Oehlke to see if he has any ideas.

Hornworm:  Manduca pellenia

Nice pictures of amazing animals!
The Saturnid caterpillar is probably of an Automeris species indeed.
The Sphingid caterpillar is most likely a Manduca pellenia.
Nice wishes from Berlin,
Bostjan

Thanks Bostjan,
We will search for some appropriate links.

Ed. Note November 4, 2014:  Identification submissions to What’s That Bug? can include three attachments and very few folks actually attach all three.  In instances where three images are submitted, we generally only post two.  We are retroactively amending this posting to contain the third image as all three are so beautiful.

Giant Silkmoth Caterpillar

Giant Silkmoth Caterpillar

Subject: Huge caterpillar found in Costa Rica
Location: Zona Norte, San Carlos, Costa Rica

Hi. I live in the Zona Norte in Costa Rica. Two nights ago, I found a huge green caterpillar crawling in our yard. It was 4-5 inches long and about 2.5 inches in diameter. It didn’t appear to have any hair or spines, or, if it did, they were very short. It also appeared to have narrow, yellow bands. The underside was black, I think. It rather looked like the caterpillar in Alice in Wonderland. In the picture, it’s next to a full size Maglite to give perspective. It made a cocoon the next day. Any help you can provide would be much appreciated.

Hi Lacey,
While we are unable to provide you with an exact species, we can tell you that this is a Giant Silkmoth Caterpillar in the family Saturniidae.
  Adult Giant Silkmoths are often large and spectacular looking.

Hi there, I woke up today (October 9) my birthday to find this guy wishing me happy birthday on my porch. Actually he was crawling through a semi deep puddle. I watched him go all over, then moved him to the park so my dogs wouldnt eat him. I searched a few sites but couldn’t find a match.
I have been in Tucson, AZ my entire life, 30 years todAy, and I have never run across one of these guys. About 2 in. Long and an inch in diameter. His spikes listen and reflect a silver color. He’s quite awesome and I’m considering it a happy birthday from Mother Nature! Thank you in advance!

Happy Belated Birthday J. Price,
This magnificent caterpillar is a Royal Moth Caterpillar in the genus
Sphingicampa, and just last week we posted another example, also from Tucson.

Sphingicampa Caterpillar

Sphingicampa Caterpillar

Hi Neil,
You have correctly identified the genus
Sphingicampa, but according to BugGuide:  “Eight species occur in America north of Mexico” and they all have similar looking caterpillars.  BugGuide reports three species in Arizona, including Sphingicampa raspa, and we do not have the necessary skills to say for certain which species you encountered.

Saturniid Caterpillar

Cabbage Emperor Moth Caterpillar

Dear dkortephoto,
Your images are beautiful, as is this Caterpillar.  The only information we can provide at this time is a family, and your caterpillar belongs to the family Saturniidae, the Giant Silkmoths.  We have contacted Bill Oehlke for assistance as he has especial interest in the Saturniidae.  We hope you will permit him to post your images to his comprehensive website if he assists in the identification.

Update:  October 3, 2014
We heard back from Bill Oehlke who identified this marvelous caterpillar as
Bunaea alcinoe, a species represented in our archives.  The more typical coloration we see is black with yellow and red spikes.  Your red individual is not as common a color variation.  This species is known as the Cabbage Emperor Moth Caterpillar.

Luna Moth Caterpillar

Luna Moth Caterpillar

Dear Paul,
Though typically green, this Luna Moth caterpillar has turned orange because it is getting ready to pupate.  The Luna Moth Caterpillar is described on BugGuide as being:  “Larva lime-green with pink spots and weak subspiracular stripe on abdomen. Yellow lines cross the larva’s back near the back end of each segment (compare Polyphemus moth caterpillars, which have yellow lines crossing at spiracles). Anal proleg edged in yellow. Sparse hairs.”
