Subject: What is this caterpillar and the hairy stuff around it?

Hi! I live in Sydney, Australia and it’s currently autumn. I saw this caterpillar on my cumquat (calamondin) tree. Do you know what kind it is? What is that hairy structure around it? Is it the start of a cocoon?

Lichen Moth Cocoon, we believe

Dear Carey,
We found an exact match to your cocoon on FlickR, but alas, it is only identified as a “wingless moth cocoon.”  We actually found that image after finding several similar looking, but not exact images, beginning with Butterfly House where there are images of the caterpillar, caterpillar in its cocoon and pupa in the cocoon of Cyana meyricki, and this information is provided:  “The cocoon made by the caterpillar is quite remarkable. It is an open square mesh cage, constructed out of larval hairs held together with silk. The hairs are too short to construct the cage directly, so the caterpillar attaches pairs of hairs to each other end to end, and uses these pairs to make the sides of the cage. The pupa is suspended in the middle of the cage, equidistant from the sides. The caterpillar even manages to push its final larval skin outside the mesh cage while forming its pupa. When the moth emerges, it appears to exit the cage without damaging it.”  We found another image of the caterpillar in its cocoon on FLickRAustralia Museum provides the common name Lichen Moth and provides this information:  ” This lichen moth makes an elaborate open mesh cocoon using the shed hairs from the hairy caterpillar which are held together with silk. The pupa is suspended in the middle.”  Now we will present our opinion.  We believe this is a Lichen Moth Caterpillar in its cocoon, after losing its hairs and constructing the cocoon, but before the final molt to the pupa occurs, so you are seeing a pre-pupal caterpillar that doesn’t really exactly resemble either the caterpillar or pupal stage as it is in transition.

Update:  May 17, 2017
We just approved a comment that the Clouded Footman,
Anestia ombrophanes, is another possibility, and images on Butterfly House tend to support that possibility.  The site states:  “They form a pupa inside a sparse cocoon made of silk and larval hairs, attached to a fence, a tree, or a wall.”

Hello Mr. Bugman! my brother is living in Guatemala, San Martín Jilotepeque. Yesterday he found this pretty caterpillar and adopted it in his house. I think it could not be a brilliant idea, but anyway we would like to know what is it. 🙂 Could you help us? It was eating coffea frond.
Thank you so much!

Tiger Moth Caterpillar

Dear Belen,
We are pretty sure this is a Tiger Moth Caterpillar in the subfamily Arctiinae.  In North America, they are commonly called Woolly Bears.

Can you tell me what he is or what he eats? Found on a sidewalk.

Clio Tiger Moth Caterpillar

Dear Brenna,
Your image is quite amusing.  It appears you have been offering this Clio Tiger Moth Caterpillar,
Ectypia clio, every imaginable vegetable except its preferred food.  According to BugGuide:  “Larvae feed on milkweed (Asclepias, Asclepiadaceae) and dogbane (Apocynum, Apocynaceae). Behr reported them on spreading dogbane (Apocynum androsaemifolium).”  It is also possible that this individual has left its food plant in search of a place to pupate, in which case it is no longer interested in eating.

Thx. And you are correct. I will get him a stick unless he buries. That would explain why he was on a sidewalk.

Hello my name is Aaron. I found this particular pod on my porch about 2- 3 months ago. I think it may be of a preying Mantua. I am not sure and would like to know. If from bad bugs. Need info to relocate to wooded area
Signature: Thank you

Tiger Moth Cocoon, we believe

Dear Aaron,
We are pretty certain this is not an egg case.  It looks to us like a moth cocoon, possibly the cocoon of a Tiger Moth from the subfamily Arctiinae.  See this Isabella Tiger Moth Cocoon from BugGuide for comparison.

Probably Painted Tiger Moth Caterpillar Hatchlings

Probably Painted Tiger Moth Caterpillar Hatchlings

Dear Dn,
These are hatchling caterpillars and all indications are that they are Tiger Moth hatchlings.  We suspect they are Painted Tiger Moth hatchlings because we live in nearby Mount Washington and there are currently Painted Tiger Moths flying to our porch light.  Painted Tiger Moths lay clusters of eggs, frequently on walls near lights, and the caterpillars, which are general feeders known as Woolly Bears, quickly disperse.
