Mendocino Saturnia Moth Caterpillar, we believe

Dear Donna,
If our identification is correct, we believe this is a Mendocino Saturnia Moth Caterpillar,
Saturnia mendocino, a caterpillar not well represented on the internet.  We located a similar image that we cannot link to, and then we located this image on iNaturalist that looks remarkably like your individual.  According to Pacific Northwest Moths:  “The last instar larva is yellow and has scoli or tubercles covered with orange hair tufts and longer white hairs.  It is illustrated by Miller & Hammond (2003).  Miller & Hammond (2007) also illustrate the young larvae that change dramatically in color pattern with each instar.”  According to Butterflies and Moths of North America:  “Caterpillar Hosts: Manzanita (Arctostaphylos) and madrone (Arbutus menziesii), both in the heath family (Ericaceae).”  Do you have those host plants growing nearby?  We will check with Saturniidae expert Bill Oehlke to verify this identity.  He may request permission to post your image to his site.

Your letter to the bugman:  Attached are two pics.  The one of a little creature which seems to be invading the garden at the moment …. looks like a kind of shongulolo (spell) because it curls ina little ball and poos on your hand …. we are not killing them but just interested where they might be coming from and what they are?   Second pic of a caterpillar we found walking the dogs… was under a plane tree and unfortunately many of them had been squashed in the road… quite sad … such lovely colors but wandering which butterfly\moth they might be… thanks very much xxxx

Your letter to the bugman:  My daughter found a caterpillar in our yard that she put in her critter cage. Our rule is you cant keep it longer than 48 hrs, well it shed its skin and turned into a cocoon so we allowed her to keep it to watch it transform. That was early September and it’s still in cocoon, still alive. What kind is it? And when should it emerge

Imperial Moth Pupa

Dear Dani,
Based on this BugGuide image, we believe this is the pupa of an Imperial Moth.  If your critter cage is not indoors, you can expect an adult Imperial Moth to emerge when the weather begins to warm.  Imperial Moths only live a few days, long enough to mate and for the female to lay eggs.  They do not feed as adults.  If a female emerges, she will attract a mate by releasing pheromones.

Hello, I found this caterpillar and I have no clue what it is. At first it seemed like an Automeris, then a Pseudautomeris, then a Molippa… Now I don’t know what it is.

Saturniid Caterpillar

Dear Oscar,
Though they both belong to the same insect order Lepidoptera, most English speaking countries differentiate between butterflies which are primarily diurnal, and moths which are primarily, but not exclusively nocturnal.  There are also structural differences between them that is clarified in the taxonomic process.  We agree that this caterpillar belongs to the moth family Saturniidae, and it also appears to be an earlier instar caterpillar.  Many online images are of more mature caterpillars that sometimes differ in appearance from earlier stages.  Our initial guess would also be the genus
Automeris, and our second guess would be Leucanella, and both genera are well represented in Brazil.  We will attempt to get Bill Oehlke, an expert in Saturniids, to attempt to provide you with a species identification.  By chance, was if found feeding on a plant?  Often knowing the food plant is a great assistance in the identification process.

Dear Manuela,
This is a Giant Silkmoth Caterpillar in the family Saturniidae.  Perhaps one of our readers will be able to supply a species identification.

Hello Bugman!  After strong winds here in Toronto Ontario, our puppy found this!  The length of the cocoon is 3 inches.  In a teardrop shape, brown.  What is it and even more importantly:  how do we keep it alive so it can complete it’s cycle?    I have it back outside temporarily in a box….but thought to carve out a spot in a log and then place the cocoon bark over and secure with wire.  There are a few holes in the bark clearly for coming out once metamorphosis occurs.  THANK YOU, Liane and Poème

Cecropia Moth Cocoon

Dear nature guardians Liane and Poéme,
We believe this is the Cocoon of a Cecropia Moth, which you can compare to this BugGuide image.  The best way to care for this cocoon is to keep it in conditions with a temperature similar to the outdoor temperature.  If you keep the cocoon indoors, it may cause premature emergence with no chance for the adult moth to mate.  Do NOT create any wire security system that will compromise the adult moth when it emerges.

Thanks Daniel!  The bark has a couple of escape holes, assuming that is for emergence.  For now I have it in a box outside with cocoon side down but not against the bottom of the bot which is folded, and not sealed shut.  I was thinking about using a rotted out log to place the bark  upside down onto the space on the log, creating a little chamber for the cocoon, then place it in our outdoors partially covered structure for protection against the elements like it would have had on the tree.  We have a log pile.
He would be safe in the box but would the log be better?
Liane and Poème
It seems either method would work, but ensure the cocoon doesn’t get either too dry or too damp.

I suspect the box will be dry…I feel like a foster parent!!
