Hello,
I am form the Netherlands and i was in 2005 in South Africa for an internship. I was at blyde river canyon (potholes)when i saw this specie. I am searching for 6 years now to find out which specie this is. I hope you can help me out?
Greetings,
Hennie

Stinging Slug Caterpillar

Dear Hennie,
We agree that this is most likely a Stinging Slug Caterpillar, however, some members of the Saturniidae family also have stinging spines.  We will post your photo and we hope our readership might be able to assist in the identification.

Karl provides a possible genus identification
December 6, 2011
Hi Daniel and Hennie:
Excluding the more common and serious pest species, tropical limacodids are always difficult to identify because of the large number of species and a general lack of online information. South Africa, for instance, has at least 117 species for most of which there is very little information to be found. However, I believe this one belongs to the genus Latoia, which includes at least a dozen South African species. Latoia vivida appears to be a very close match and I believe this is probably the correct species, but I cannot be certain. Here is a link to another photo. Coffee is apparently the preferred larval host plant and the species is considered a serious pest on that crop in central and southern Africa. By the way, I think this may be the same species that was posted on WTB by Adrian back in January, 2008. Regards.  Karl

Variegated Fritillary Chrysalis

Hi Devon,
This is the Chrysalis of the Variegated Fritillary,
Euptoieta claudia, and you can see a photo from BugGuide to verify our identification.  The adult is a wide ranging lovely orange butterfly.  The name “chrysalis” can be traced to the Greek word for “gold” and this lovely Chrysalis is an excellent example of the gold coloration that is found in so many butterfly pupae.

The most beautiful caterpillar in the world from Kenya

Caterpillar found in Africa

I am wondering what kind of butterfly this would turn into, and what the species of caterpillar is.

Beautiful Caterpillar from Kenya

Hi Lauren,
This is just about the most beautiful Caterpillar we have ever seen.  We don’t know what it is but the head reminds us of a Skipper Caterpillar.  Most Skipper Caterpillars we have seen have green bodies, though coloration has very little to do with genera classification.  We actually prefer not to research this at the moment because we want to spend some time imagining what the butterfly (and we really believe this is a butterfly) would look like upon metamorphosis.

Anchor Stink Bug eats Monarch Caterpillar

What is this pink and black beetle?
Location: Down East Maine – field
November 17, 2011 9:20 am
I have tried to find out – but not 100% sure – closest I could find was a Calligraphic Beetle? But the shape of his back-end is more pointed than the rounded Calligraphic Beetles I found images of on the Bug Guide website, and the black markings don’t fully match up. This beetle was definitely pink too. I would love your help:) It definitely was taking this monarch caterpillar with it!

Dear Caroline,
The predator in this Food Chain drama is an Anchor Stink Bug,
Stiretrus anchorago, and we identified it on BugGuide which notes:  “Adults feed on the larvae of beetles, butterflies, and moths. Stiretrus anchorago is considered an economically beneficial insect, feeding on the larvae of the Mexican Bean Beetle, among other pest species.”  It seems late in the season for this to occur.  When was this photo taken?

The photo was taken August 8th.  And thank you soooo much for getting back to me.  Very exciting to know who that was in my backyard!

Deathshead Hawkmoth Caterpillar from Namibia

Namibian Arthropods
November 17, 2011
Dear Daniel, Many thanks for your 3 messages and all the details they contain. I’m not e-maiing from Namibia but from the U.K. but the delay in responding is because we don’t have the computer on daily. I’ve attached to this message 2 more photos not for identification as I believe they are of a Death’s Head Hawkmoth Caterpiller but I hoped you  might like to see them or use them.
I wonder however if I may submit 2 further pictures for identification, again both taken in Namibia.
Kind regards, Roger.

Hi Roger,
There are several species called Deathshead Hawkmoths from the genus
Atropos, and this is surely one of them, but we haven’t the time to research the species found in Namibia at the moment.  If you send additional photos, please use our standard form and please attach only a single species per submission.

Habitat for a Polyphemus Caterpillar

Food and Environment for Polyphemus Moth Caterpillar?
November 13, 2011 1:25 pm
Hi!
My husband found one of these crawling the grass at our neighborhood playground in Dallas, TX. We’d love to try and see it through to becoming a moth. What should we provide it for it as far as food, habitat etc? Interestingly enough, a few weeks ago we were given a butterfly habitat(large mesh cylinder with a lid).
Thanks!

Polyphemus Caterpillar from our archives

Dear Rachel,
Your butterfly habitat should do fine.  You can also use an old aquarium with a screen top.  Chances are quite good that when the Polyphemus Caterpillar left the trees it was feeding upon, “birch, grape, hickory, maple, oak, willow, and members of the rose family” according to BugGuide.  The caterpillar will spin a loose cocoon around a large leaf, so provide some old, but not dried leaves on the floor of the habitat for the Polyphemus Caterpillar to spin its cocoon.  Here is a nice post from our archives showing stages of Polyphemus metamorphosis.

Queen Caterpillar

Mutant Monarch Caterpillar?
Location: West Los Angeles
November 14, 2011 12:06 pm
Hi Bugman,
We’ve had dozens of Monarch caterpillars this year (best year in a long time). Their colors varied somewhat, but all had rings of colors the length of their bodies.
The caterpillar pictured was found on a milkweed plant, but wasn’t interested in eating. It also did not appear large enough to begin chrysalizing (is this a word?).
As you can see, it does not have rings, but spots, and an additional set of ”false” antennae near the middle of its body.
So is this a Monarch caterpillar or something else?
Thx, Jeff

Hi Jeff,
This is noteworthy for Los Angeles.  What exciting photographs to post, especially since they are from Los Angeles.  There are several other Milkweed Butterflies in the Monarch genus
Danaus, and this is another member of the royal family.  We believe this is the Queen Caterpillar, a species reported from California according to BugGuide.  Your individual is darker than the images posted to BugGuideQueens are darker than Monarchs.

  On a side note, we are formulating written responses to interview questions for a Russian magazine, F5.  One of the questions we have been struggling with is 15.  After having studied bugs for so long, have you learned anything important from them?  And the answer is:  “Yes I have.  I have learned that we are all individuals.  Just as no two people look alike, no two insects look exactly alike, but some are very similar.  I learned this after seeing a photograph of a Queen Caterpillar that was much darker than photos of Queen Caterpillars I found on legitimate websites like BugGuide.  I have learned that even if I have difficulty telling two insect species apart, insects have no trouble recognizing their own species.  Species are just close to one another on the evolutionary scale, and they differentiated due to global distribution.  When you cut off a gene pool, it differentiates from disparate groups and eventually it forms a race, that if they cease to intermingle, might evolve to a point where they can no longer reproduce together.”

Hi Daniel,
Thanks for your reply – I’m hoping to see a Queen butterfly as well and was wondering of there is a way to tell the chrysalis from that of a Monarch.  The pictures in BugGuide don’t show any distinguishing features.  Do you know of any?
Thx,  Jeff

Alas, we don’t know how to distinguish the two chrysalides.  We will copy Keith Wolfe to see if he has any insight.

Keith Wolfe Responds
Jeff, please see this rather crude comparison using Internet photos . . .
http://home.comcast.net/~bflyearlystages/Differentiating-US-Danaus-immatures.doc
. . . which was quickly put together many years ago for a student I was mentoring.
Enjoy the wonder!

Had a stroke of luck yesterday when I spotted a Queen caterpillar starting to chrysalize.  Now I just need to be there when she emerges.

Achemon Sphinx Caterpillar

Caterpillar in Malibu, CA
Location: Malibu, CA

Dear Bugman, I found this large caterpillar crawling in my garden. It was not on a plant but I put some clover in a box with it. I’m trying to find out what kind of butterfly or moth it’ll turn in to. Can you identify it?
Thanks!

Achemon Sphinx Caterpillar

Dear Bu Girl,
Though your photo does not show the markings on the side of this individual very well, we believe you have photographed the caterpillar of the Achemon Sphinx.  Sphinx Moth caterpillars are called Hornworms because they usually have a caudal horn, however, the Achemon Sphinx sheds its caudal horn as a young caterpillar, leaving a caudal spot or “eye” that is barely visible on the right side of your photo.  According to the Sphingidae of the Americas website, the caterpillar of the Achemon Sphinx feeds upon:  “Grape (Vitis), Virginia Creeper (Parthenocissus quinquefolia) and other vines and ivies (Ampelopsis).”
