Cocoon of a Giant Silkmoth

Dear Carol,
This is the cocoon of a Giant Silkmoth in the family Saturniidae.  A Cocoon is generally a silken structure that is spun, possibly incorporating leaves, branches or the hairs from the caterpillar in its construction.  The cocoon helps to protect the naked pupa inside.  The pupa of a butterfly is often called a chrysalis.  We hope that helps some with the proper terminology.  We believe this may be a Polyphemus Moth Cocoon (see BugGuide) or possibly a Luna Moth Cocoon (see bugguide), though the cocoons of the Luna Moth generally fall to the ground among leaf litter where a blanket of snow helps to insulate them from the cold.

Dear Katy and her dad,
Can you confirm if the caterpillar pictured metamorphosed into the attached chrysalis, or if they are different species?  We will contact Keith Wolfe to see if he is able to identify this species which we believe is a member of the Brush Footed Butterfly family Nymphalidae.

Daniel,
We are not completely sure that they are the same but the chrysalis
was in the same place we left the caterpillar 3 days prior.  Katy’s
mom says she thinks she saw it already attached  there in yellow form.
Thanks for your help!

Keith Wolfe responds.
Dear Katy, Dad (plus Mom), and Daniel,
This is the larva and pupa of the Large-spotted Acraea, Acraea zetes.  I will write more after returning home tomorrow.  Merry Christmas!
Best wishes,
Keith

Daniel and Kieth,
Thanks much for the ID and Merry Christmas.
Katy and her mom and dad.

Keith Wolfe elaborates:
December 28, 2011
Hello again Katy, Dad, and Daniel,
Yes, with luck, your chrysalis will metamorphose into Acraea zetes (http://ftp.funet.fi/pub/sci/bio/life/insecta/lepidoptera/ditrysia/papilionoidea/nymphalidae/heliconiinae/acraea/index.html#zetes); here’s the same caterpillar from Gabon — http://www.flickr.com/photos/31963237@N00/455607804/.  However, with something like 135 species of Acraea recorded from the DRC, most of whose immature stages are unknown, it’s entirely possible that my long-distance ID is wrong.  Thus, please let us know the outcome, preferably showing the resulting butterfly to a local authority or carefully comparing it to a reliable reference.  Disclaimer: the hyperlink appearing in my initial response was inserted by the ever-helpful Bugman.
Cheers from a chilly California,
Keith

Keith,
Thanks again for sharing your wealth of knowledge with us!!  We brought the chrysalis into the house with hopes to see it emerge and if lucky, document the event as it occurs.  At the very least we will get pictures of the emergent butterfly before releasing it .
Stay warm and Happy New Year to you both.
Katy and her dad.

UPDATE:  December 29, 2011
Daniel and Keith,
We got emergence !  Unfortunately no one was home when it happened to get pictures of the process but we got pictures of the butterfly here :

Does it look like Acraea zetes after all ?
Thanks
Katy

Daniel and Keith,
We were lucky to find the butterfly after emerging yesterday.  Unfortunately everyone was out of the house when the event occurred sometime between noon and 4pm.   You can see pictures of the chrysalis that morning and the butterfly in the series created here.  I hope species confirmation can be made with picture of the butterfly form.

Thanks again.

I believe this is a Sphinx Moth. It is feeding on Crown of Thorns. I’ve seen them over the summer before, but never in December.
PS. LOVE your site. Thank you

Ello Sphinx Caterpillar

Dear Anthony,
Thanks for the compliment.  We believe we have correctly identified your caterpillar as an Ello Sphinx,
Erinnyis ello.  We did the original identification based on information on the Sphingidae of the Americas website which indicates that they feed on plants in the family Euphorbiaceae which include poinsettia and crown of thorns.  The caterpillar is also reported to be quite variable in coloration.  BugGuidenotes:  “Larval characters: (2)  Horn reduced to a low point, arising from an elevated angular hump.  In the last instar, the horn is reduced to a nub.  Eyespot over the third thoracic segment is hidden in the resting caterpillar.  Ornately banded thoracic and prolegs.  Length to 7cm.   Erinnyis spp. caterpillars come in a seemingly endless variety. “

Monarch Chrysalis Christmas Tree

Ed. Note:  We thought this was such a lovely photo and such a marvelous example of a Bug Humanitarian that we are passing on the holiday greetings to our readership regardless of faith or denomination.  As arguably the most intelligent life form on this planet, we humans have a responsibility of stewardship for the environment, including the lower beasts.

My Christmas tree this year
Location:  This is in Jacksonville, Florida, on the banks of the beautiful St Johns River.
December 20, 2011
This is my Christmas tree this year, and I love it.
A late hatching of Monarch caterpillars during a cold snap made me carry many of them inside for protection.  Now they’ve gone into chrysalis form (I have video!).  Obviously, I transferred them from their chosen sites (not always good choices) to a little bonsai tree, where they’ll all have clear “take-off” points.
The black chrysalis (on the right) is about to hatch – they turn black before they break out.
Merry Christmas!
Lane

Monarch Chrysalides as holiday ornaments

Dear Lane,
Thank you for the lovely holiday greeting which we are featuring as a post.  We are also tagging you as a Bug Humanitarian because of your rescue intervention.  Could you please provide us with a location for the photo?

Of course!  This is in Jacksonville, Florida, on the banks of the beautiful St Johns River.
I must add a sad but educational note:
These Monarch caterpillars were laid and fed on first-year Mexican milkweed.  But I’ve learned that that species harbors a parasite that kills the caterpillars before they can chrysalize IF they feed on second-year plants.  Mexican milkweed (not native to Florida)  tends to live through the winter so produces second-year plants.  It’s a real threat to Monarchs here.
The sad part is that I had a dozen healthy caterpillars but my plants were eaten up so I went to a friend for foliage and her clippings must have  come from older plants as all the caterpillars that fed on it died.  It was very sad to see healthy caterpillars collapse and die a slow death from the parasites.
I’ll pull up this year’s plants and use native species next year as they do die back in the winter.
Thank you for your fascinating and helpful site.  You do great good for the bugs of the world – and the humans too.
Happy holidays and New Year,
Lane Welch

Thanks for the information on the milkweed dilemma.  We were unaware of that threat.  Various native milkweed species are found in so many parts of the world that we would always encourage butterfly gardeners to plant native whenever possible.

Dear Daniel,
I’m very honored and proud to receive the Bug Humanitarian citation.
My tree could be a “tree of life” or “tree of renewal” – its significance is equally applicable to any religion or frame of belief (or lack thereof).
No one can be offended by the breathtaking beauty and complexity of all of nature.
Best wishes,
Lane

I agree.  Before I knew about the problem I just bought what was at the big-box hardware store.  Maybe the Mexican species, being so hardy, is easier to ship – that or some other cost-motivated factor is probably behind it’s availability.  Next year I’ll seek out native plants.
Speaking of those big stores, their purchasing power has effects on the environment of which most individuals are unaware.  For example, cypress mulch is produced by horrible destruction to Florida and Louisiana coastal areas.  Cypress mulch should not be produced – they’re slow growing and no such thing as an excess of them.  I’ll get off my soapbox now!

Why stop now Lane?  We sometimes feel we are perpetually on a soap box, preaching about unnecessary carnage and the like.

Hello,
This creature was photographed in Kasanka National Park, Zambia. It was crawling on the hood of a stationary car, possibly fell down from an overhanging bush. Date: May 10, 2011.
Any idea, at least to genus? I’d be grateful. Thanks.

Dear Monika,
That is sure one crazy looking Bagworm with its grassy bag.  Bagworms generally create their bags from the foliage of the plants they feed upon.  If you are able to identify the plant species it is feeding upon, it will facilitate a species identification for the Bagworm.

Gulf Fritillary Caterpillar

Dear Amy & Tony,
We suspect that there is a passion flower vine nearby since this is a Gulf Fritillary Caterpillar and that is the food plant.

Thanks! You are correct! The vine in our garden is a passion flower!
Cool! I guess this butterfly has extended its range quite a bit as we live in NorCal not southern Cal.
Amy & Tony

The range of the Gulf Fritillary has expanded significantly with the cultivation of passion flower.

Imperial Moth Caterpillar

Huge Green Caterpillar

Hi, I was pruning our coco plums (Chrysobalanus icaco) today Dec six when I found this caterpillar chowing down. He is twice as long as my thumb and as wide. I live in Fort Myers FL. I searched your site to find a picture & info. about this caterpillar, but did not find any. Maybe this is a different species! Thanks in advance for your help!

Imperial Moth Caterpillar

Dear Carol,
These are positively gorgeous photos of an Imperial Moth Caterpillar,
Eacles imperialis.  Thanks for also providing the name of the food plant, the coco plum.  A recent posting of this species from September shows a brown coloration that could be either a color variation, or more likely, the darkening of the pre-pupal caterpillar that usually leaves its food plant to find an appropriate place to dig into the soil to undergo metamorphosis.

Sphinx Moth Caterpillar

Is this a swallowtail caterpillar?
Location: Riviera Nayarit (Puerto Vallarta)
December 4, 2011 4:27 pm
Hi there, we were in the Riviera Nayarit (Puerto Vallarta area)late November and one evening as we left the resort bar we came across this bug. I’ve been looking around and I think it’s a swallowtail, but it’s also more gross than any of the swallowtails I’ve seen in pictures so far. Could it be that the caterpillar is in late pupa stages? Is it even a swallowtail? Any help you can give would be appreciated.

Sphinx Moth Caterpillar

Hi Michelle,
This might be a Swallowtail Caterpillar, but some Sphinx Moth Caterpillars also have eyespots.  Sadly, your photo does not show the anterior end where a caudal horn is found on most Sphinx Caterpillars.  Hopefully we will have time in the future to allot to trying to determine a species identity.

Update courtesy of Karl
Hi Daniel and Michelle:
I think your second hunch is probably correct. It looks like a Sphinx caterpillar in the genus Madoryx (Sphingidae: Macroglossinae). It looks very similar to the pre-pupal M. plutonius specimens on the Area de Conservación Guanacaste (ACG) site. This species apparently doesn’t occur as far north as Mexico but a subspecies, M. plutonius dentatus, lives in Mexico and Belize. And yes, this appears to be one of those hornless varieties of Sphinx caterpillars. Regards. Karl

Hi Karl,
Thanks for taking the time to do this bit of sleuthing.
