What kind of animal is this?
Hi,
I would like to know if you people know what kind of animal this is. Country: Guatemala. Region: Petén. City: Tikal. Size: 6-7 centimers. We touched the animal with a wooden stick and then it made some attack move or something. His tongue came out like some sort of snake. The movie were it can be seen is over here: http://jasperstevens.nl/mexico/beest.mov Thanks in advance,

hi Jasper,
This is some species of Swallowtail Butterfly Caterpillar, probably in the genus Papilio. The tongue you describe is a scent gland known as an osmetrium. We will try to identify the species of this pretty caterpillar.

Hello again, Daniel.
a few other IDs and correction.
Yes, this wandering prepupa (compare its faded coloration to this caterpillar still feeding on an avocado leaf: http://www.flickr.com/photos/missingchandra/76362584/ ) will soon metamorphose into one of the 11 or so butterflies in the ” Pyrrhosticta ” group of Papilio swallowtails — P. cleotas ,P. garamas ,P. victorinus , etc.
I hope the above information is helpful.
Best wishes,

pink caterpillar
Dear Bugman,
I found this pretty bubblegum pink caterpillar this afternoon eating my scarlet runner beans. My daughters and I have really enjoyed your site, and thought about you right away. I’m attaching two pictures, and I hope that you can help us.

Hi Sherry,
We believe this is some species of Slug Caterpillar in the family Limacodidae, but we were unable to locate an exact match on BugGuide.
Update: (07/21/2008)
Sirs – The ” Probably Unknown Slug Caterpillar (07/11/2008) pink caterpillar” most likely is in the family Lycaenidae. See http://www.dallasbutterflies.com/Butterflies/LARVA/pics/henricilarvae.jpg for an example.

We live in Orlando, Florida and my husband found these caterpillars (?) on our Key Lime Tree. Can you tell us what kind they are? They had amazing long red forked tongues. We are a crowd of bug lovers but we have never seen these and they made us a bit nervous with the long forked tongue. Thank you for any information.

Hi Andrea,
These are Giant Swallowtail Caterpillars, Papilio cresphontes. It is widely accepted that they mimic bird droppings to avoid getting eaten. The red forked “tongue” is a scent organ knows as the Osmetrium. Giant Swallowtail Caterpillars are harmless and develop into beautiful butterflies..
Caterpillar ID?
Hey Bugman!
I found this caterpillar enjoying my purple verbena. I looked on your website and Bug Guide, I couldn’t find it. I thought it might be a slug caterpillar because of its shape, but it doesn’t have stingers on it. It’s a mauve color and I tried to get a super clear photo of it, but I didn’t have much luck. I love your website. It’s the first one I check when I need to ID something. Thanks for all of your hard work!! Thanks!

Hi Sheila,
Your caterpillar is one of the Gossamer Winged Butterflies in the family Lycaenidae, probably one of the Blues in the subfamily Polyommatinae. It looks quite close to a photo of the Ceraunus Blue caterpillar posted to BugGuide. The species is found in Georgia
