After a large amount of picture comparisons and forum searching, I think I have this one pegged as a basket bug. I sent an identification request this morning still thinking it was hornetsnest of some kind.

We agree with your identification.  Moths in the family Psychidae are commonly called Bagworms because the larva construct “bags” from silk and plant parts that they live inside as a means of protection.

Noticed this yesterday while working in the yard. It’s dangling from a live-oak tree. I’ve been here 8 years and never seen one here before, or anywhere else I’ve ever lived. If you’re the size of a bug I think this is a marvel of construction. As far as I can tell those are very neatly cut or chewed twigs. Notice the hanging apparatus, it almost looks like braid, or rope.
It is approx 3″L x 14/16″ at the widest point. I showed it to a friend asking if he knew what it was, and his reply was, “Mini air-beavers?”
What’s your guess?

Dear Sarah,
Though the thought of mini air beavers is tremendously amusing, this is actually the pupa of a Bagworm, a moth in the family Psychidae.  Construction on the bag begins with the young caterpillar and the bag is enlarged as the caterpillar grows.  The Bagworm caterpillar drags around its bag which acts as shelter and camouflage, and eventually the Bagworm caterpillar pupates within the bag after attaching the bag to a brand or fence.  Your Bagworm is in the pupal stage.  When it is mature, a winged male Bagworm moth or a flightless female Bagworm moth will emerge.

This was crawling on the sidewalk and inching along and appeared to be dragging the ”salad” behind it…sort of an insect Carmen Miranda …any ideas? It was about 3~4 inches long…
Just curious!

Hi Don,
This is a Bagworm, a caterpillar in the family Psychidae.  We believe it is an Evergreen Bagworm,
Thyridopteryx ephemeraeformis, based on photos posted to bugGuide.

Dear WTB,
Would you tell me what this bug is? I found it while strolling in a local park. It was slowly dragging itself along the pavement. I tried poking it with a stick to see if it would come out of that ”shell”, but some kind of orange-ish blood poured out!

Dear Luis,
We believe this is a Bagworm, the caterpillar of a moth in the family Psychidae.  Bagworms construct mobile homes for themselves from the plant parts that they feed upon.

Hi, my name is Tadeo, i am 10 years old and i discovered this strange cocoon in a just planted tree. After a while i saw that the cocoon was at a different place as the previous watch…so i started to pay more attention to it. Just tonight i found out that inside the cocoon lives a big worm…but i was not sure it was a SilkWorm….I have HD pictures…Can you please help me identify it…
Thanks a lot

Hi Tadeo,
This Bagwormis most likely in the family Psychidae and it will eventually pupate within its bag when it will become a stationary cocoon.  Your photos are of a beautiful quality and they are a nice addition to our website.  We are sorry we cannot identify your Bagworm to the species level.  We don’t receive many submissions from Uruguay to our site, so thank you for sending your sighting.

Hi Daniel, thank you very much for your reply…. if you can…i have some other questions….
I want to know if this will be a buterfly…I want to know also how much time can take that so i can see and take pictures from all the process. Unfortunatelly the tree where it was at the beginning broke and now we put some tree leaves near him to eat…but maybe we can generate a better place…..
Thank you very much… i am really very interested and your website is very very cool.

Hi again Tadeo,
Bagworms are actually moth caterpillars and they are not especially showy.  Interestingly, female Bagworms are wingless and they do not venture far from the bag when they eclose or emerge from the cocoon.  Once she has mated, the female Bagworm lays eggs inside her bag for the next generation.

Hi Frank,
This is a Bagworm in the family Psychidae.  We located an Ecological Observations in Singapore Blog posting of Bagworms that has one image that somewhat resembles the head of your Bagworm.  We cannot be sure they are the same species.  Bagworms construct their bags from pieces of the plants they feed upon.  The bags act as camouflage and protection.
