Found 2 of these guys on my Pothos plant this morning, and no idea what they are.
They crawled right onto the stick and I moved them away to a tree.

Definite Tussock Moth Caterpillar

Dear Frog,
This is a Tussock Moth Caterpillar in the genus
Orgyia, and because of its pale coloration, we believe it is a Definite Tussock Moth Caterpillar which we identified on BugGuide.

Hi there. I found this caterpillar along with some baby caterpillars and what could be eggs on my Virginia creeper vine. There are holes in the leaves. Not sure if the babies are the same caterpillar.
It looks like a shiny brown globe on its butt, interesting… Is it a fake eye to distract predators?

Abbott’s Sphinx Caterpillar

Dear Maggie,
This is an Abbott’s Sphinx Caterpillar,
Sphecodina abbottii, which we verified by comparing your individual to this BugGuide image.  According to BugGuide:  “Larvae feed on Grape, Vitis and Ampelopsis” and though it is not mentioned, Virginia Creeper is in the same family as grape and many caterpillars that feed on grape will also feed on Virginia Creeper.  BugGuide data does not report any Manitoba sightings, and Sphingidae of the Americas does not list the species among those found in Manitoba.  Though Sphingidae of the Americas does not include any reports from Manitoba, the species page does indicate a caterpillar “was spotted on Virginia Creeper in early August in Quebec.”  We are going to contact Bill Oehlke to inform him of your Winnipeg sighting which might be an indication the species is moving north due to global warming.  We hope you will allow him to post your image on his very comprehensive site.

Absolutely. I also have some pics of baby caterpillars, and eggs, which could be the same species – all in the same vicinity of the adult. I’m including them here…
I have spotted a Waved Sphinx here as well. Thanks for the id. I hope it doesn’t destroy my vine, but I’ll leave it.

Possibly Sphinx Moth Eggs

Dear Maggie,
The eggs do resemble those of a Sphinx Moth and the caterpillar with the caudal horn is definitely a Sphinx Moth Caterpillar, however there are other species that feed on Virginia Creeper and we cannot state for certain that your early forms are Abbott’s Sphinx.  According to the Sphingidae of the Americas, the Achemon Sphinx is reported from Manitoba and the site states:  ”
Eumorpha achemon larvae feed upon Grape (Vitis), Virginia Creeper (Parthenocissus quinquefolia) and other vines and ivies (Ampelopsis).

Hello bugman,
My wife Kathy and I found several congregations of these 4 inch long ringed caterpillars at La selva biological station in Costa Rica. Any idea what the species is?
Thank you for your input.

Unknown Caterpillars

Dear George,
WE would have thought that caterpillars this strikingly marked and colored would be easy to identify, but alas, that is not the case.  We cannot even state for certain if they will metamorphose into butterflies or moths.  We will post them as unidentified and perhaps on of our readers will have better luck with an identification than we have had.

Hi Dan,
Thank you for your appraisal of the image.   I tried on the internet and could not find another image of these caterpillars.  I will keep trying.

I have a plant that just popped up in my garden and think it’s a lamb’s ears. Each tip of the tallest 5-7 branches have been folded up into caterpillar homes. See picture… Do you have any idea what they might be?
Thank you!

American Lady Caterpillar

Dear Judy,
This distinctive caterpillar is an American Lady Caterpillar,
Vanessa virginiensis.  According to BugGuide:  “Larvae feed on Cudweeds, Everlastings and Pussytoes – Gnaphalium, Anaphalis, Antennaria.”  BugGuide also makes reference to the caterpillars making “leaf shelters” and there is a nice image on BugGuide with the caption “The larva weaves the leaves together and feeds inside the shelter.”

Thank you Daniel,
That’s exactly what they are doing – “weaving” for shelter. I see no signs of them feeding on any leaves. I hope they survive. I look forward to seeing them as butterflies. 🙂

Dear Judy,
We would love any images you can send of chrysalides or adults once they emerge.

Mating Gulf Fritillaries

Dear Jeff,
It is going to take a chunk of time to correctly edit the posting to contain your awesome images depicting the life cycle of the Gulf Fritillary,
Agraulis vanillae, a common Southern California butterfly.  We have decided to begin the posting with your awesome image of a pair of mating Gulf Fritillaries, a logical place to begin a life cycle, and we will add to the posting as we reformat your images. This has prompted us to initiate a new tag of Buggy Life Cycles to house both this and your previous Anise Swallowtail documentation.

Hi Daniel,
This is the second time you’ve spotted a parasitic wasp in one of my pictures.  Is there anything I can, or should, do about this?  I understand the wasp has as much right to exist as the butterflies, but I can’t help feeling protective over the caterpillars.
Thx, Jeff

Gulf Fritillary Chrysalis

Sorry Jeff,
We can’t think of a way for you to protect the early stages of butterflies from parasitoids unless you raise the caterpillars in a container with a fine mesh screen.

I am a hopeless butterfly enthusiast who came across this interesting caterpillar crawling along the
paved trail in our state park. I am familiar with the common butterflies found in our area, but my
research provided no matches for this larva. It was clearly in the wandering stage, seeking out a place to pupate. I hope you will be able to solve my little mystery. I would love to know to which
species it belongs! Many thanks in advance.

Our Automated Reply:  Thank you for submitting your identification request. Please understand that we have a very small staff that does this as a labor of love. We cannot answer all submissions (not by a long shot). But we’ll do the best we can!

In the interest of not wasting your valuable time, I want to let you know that I
was able to identify my butterfly larva.  It is a Mourning Cloak caterpillar!
Thank you for the great work you do!

Mourning Cloak Caterpillar

Dear Kathy,
We are thrilled to post your image of a Mourning Cloak Caterpillar.  Theyy do wander in search of a suitable site to undergo metamorphosis, and we have several images in our archive of Mourning Cloak chrysalides under the eaves of homes.
