Cecropia Moth Cocoon

Cecropia Moth Cocoon

Dear Kyla,
This appears to be the Cocoon of a Cecropia Moth, one of the Giant Silk Moths found in North America.
  According to BugGuide:  “Larvae feed on leaves of various trees and shrubs including alder, apple, ash, beech, birch, box-elder, cherry, dogwood, elm, gooseberry, maple, plum, poplar, white oak, willow.  may also feed on lilac and tamarack.”  The adult Cecropia Moth is a beautiful creature.  Cecropia Moths overwinter as cocoons and the adult should emerge very soon.

Dear brucama,
These are Cabbage Tree Emperor Moth Caterpillars,
Bunaea alcinoe, and they can be very plentiful at times.  They are considered edible.  The adult Cabbage Tree Emperor Moth which is pictured on iNaturalist is quite beautiful.

Dear Don,
These distinctive caterpillars are Cabbage Tree Emperor Moth Caterpillars,
Bunaea alcinoe, and they are more typically black in coloration.  This is an edible species.

Hi, Bug Folks,
I’ve seen individuals of this caterpillar in the past, but never masses like this. They are feeding on a common wild shrub called “polly redhead” in Belize. I’ve seen it in FL nurseries as “fire bush”.
So, WTB?
Thanks.

Stinging Silkworms

Stinging Silkworms

Dear Tanya,
We believe these are stinging Silkmoth Caterpillars in the genus
Leucanella, but in doing some research, the only species we can substantiate from Belize is Leucanella acutissima, but we did not locate an image of the caterpillar.  We are going to contact Bill Oehlke to see if he can substantiate the species, and since he is lacking images of the caterpillar of  Leucanella acutissima, we suspect he may request permission to post  your images to his comprehensive site.  If this is another species in the genus, he may also want to request permission to post the images as a record of a new species in Belize.  We hope you will grant him permission.

Update:  We found some images of the caterpillar of Leucanella acutissima on Bio-Nica and they look correct.

Bill Oehlke responds
Daniel,
Those seem a good match for acutissima larvae. There are a couple of other species documented from Mexico that have not been documented fromBbelize, but I would not be surprised if they are also present
In Belize.
Bill

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

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.
