What kind of caterpillar is this. What will it turn into.

Cabbage Tree Emperor Moth Caterpillar

Dear Mr from Uganda,
This is either an Emperor Moth Caterpillar,
Bunaea alcinoe, or a closely related species in the same genus.  Commonly called the Cabbage Tree Emperor Moth Caterpillar, this species is edible.  We believe your individual has finished eating and it is searching for the ideal place to pupate.  The adult Cabbage Tree Emperor Moth is a gorgeous creature.

I found a group of eggs outside on the floor which are from the Anisota virgeniensis family. what should I do with them? what do they feed on? how long do they take to hatch? I’m trying to figure out what tree to put them on, what leaves..

Oakworm Eggs

Dear Natasha,
We are impressed that you were able to identify these eggs and puzzled why you did not know the answer to some of your questions once you had an identity.  Your eggs do indeed look like the eggs of a Pink-Striped Oakworm,
Anisota virginiensis, based on this BugGuide image.  According to BugGuide:  “Larvae feed on leaves of oak.”  We suspect the eggs will likely hatch when new growth is sprouting on the oaks.

I had put them on an oak tree, but I wanted to make sure I was doing the right thing because I would’ve been upset if I didn’t. I tend to overthink things and I like to be re-assured of an answer. Thank you for your response.

We are tagging your posting with the Bug Humanitarian Award.

Found this walking “train” of caterpillars today in Cayo, by the Mopan River in Belize. There were like 35 of them, coming down from a tree, each about 5 cm long. The green hair is toxic, got itchy and painful little bumps when I held one.

Automeris Caterpillar

Dear Daga,
This is a Giant Silkmoth Caterpillar in the genus Automeris, or a closely related genus.  It might be Automeris metzli which is pictured on the Kirby Wolfe Collection, but we are not certain.  We will contact Bill Oehlke to see if he can provide a species identification.  He may request permission to post your images to his comprehensive site as well and we hope you will grant permission.  The procession image is especially interesting.

Automeris Caterpillars

Dear Daniel,
Oh WOW! this is an amazing moth! Thank you very much for responding. Of course you have permission to post the images- I could not find a similar caterpillar on google just searching for green hairy caterpillar Belize…but I came across your wonderful site and actually identified another bug there (fig sphinx caterpillar). There is so many interesting insects here, but caterpillars specially are catching my attention as they transform to something completely different. Thank you very much again!

Subject: Moth Pupa?

Hello, Bugman! Been a big fan of your site for several years now, friend in my Master Gardners group told me about your site. Great work you are doing!
I found this gigantic pupa on the ground after pruning some Mountain Laurel on our mountainside. (We live outside Stanardsville, VA, about 8 miles from the Skyline Drive. THout it was dog poop until I looked closer, touched it and it wiggles! I put it in a big jar and put it back outside on the porch. We are having a few warm days, but expect more cold weather befor Spring arrives (today is Feb.24, 2017). I’ve looked at your photos of the Luna and Polyphemus moths, but mine doesn’t resemble them. What do you think it is?

Imperial Moth Pupa

Dear Ann,
We believe you searched the correct family, but not the correct species.  We believe this is an Imperial Moth Pupa, and the adult Imperial Moth is a lovely yellow and purple creature.  According to Featured Creatures, one listed host plant is “
Sassafras albidum (Nutt.) Nees    sassafras    Lauraceae” and since the family is the same as Mountain Laurel, that may also be a host plant, though we are having trouble confirming that suspicion at this time.  Perhaps one of the well recognized host plants are also in the vicinity.  According to BugGuide:  “Larvae feed on leaves of Bald Cypress, basswood, birch, cedar, elm, hickory, Honeylocust, maple, oak, pine, Sassafras (Sassafras albidum), Sweetgum (Liquidambar styraciflua), sycamore, walnut.”  You might want to consider returning the pupa to the safety of the leaf litter where you found it, though allowing the adult to emerge in captivity might be a wondrous experience for you.  We would urge you to keep it in a sheltered location not influenced by artificial temperatures.  Thanks for your kind words regarding our humble site.

Thanks for such a prompt response!   I will certainly return the pupa to where I found it.   I’d much rather it have a normal life!  I can now find a photo of what it will become.   Again, thanks for your ongoing hard work and help for those of us who have a love of nature and the wonders around us every day… when we can take a few moments to take a closer look at what we find and have a resource like yours to find answers to our questions.   All best wishes for continued success!  A.

Life Cycle of Argema mittrei by Bostjan Dvorak

Happy New Year Bostjan,
Thank you for submitting your beautiful drawing. 
Argema mittrei is really a beautiful Giant Silkmoth.  While we do not have any images on our site of that species, we do have an image of a relative from the African mainland, Argema mimosae, on our site.  We also have an image of what we believe to be the Caterpillar of Argema mimosae.  Perhaps you can let us know if that identification is correct. Mada Magazine has a nice article on the Madagascar Moon Moth or Comet Moth.

Io Moth Caterpillar

Dear Alison,
Your caterpillar is that of an Io Moth.  Your dorsal view hides the dramatic red and white stripes on the side of the Io Moth Caterpillar.  Handle the Io Moth Caterpillar with caution as they have stinging spines.  The adult Io Moth is a beautiful Silkmoth with stunning eyespots.

Oooo, thank you. I let him crawl on a credit card and then put him on the tree.
Thanks again!
Alison Johnson
