I’ve seen these all over my house when I moved to Florida. I’m from Michigan and have never seen these? Please let me know what they are.

Bagworms

Dear Y. Diaz,
You have Bagworms, caterpillars from moths in the family Psychidae that construct a “bag” from silk and plant material from their host plants.  Bagworms live inside the bag and when it comes time for metamorphosis, they frequently leave the plant upon which they have been feeding and anchor the bag to a sheltered location where they pupate.  We suspect these stationary Bagworms are in the pupal state.

I found this on my window this morning when I opened the blinds. It was on the outside. I went out to look at it and it looks like it is making a cocoon? It looks like tree bark. The pictures were taken in Clermont Florida in September my me. I cannot find it anywhere on line.

Bagworm Cocoon

Bagworm Cocoon

Dear Lynn,
This is a Bagworm Cocoon.  Bagworms are a family of moths, Psychidae, whose larvae construct “bags” out of plant material, generally the plants upon which they are feeding.  They carry around the bag for protection, and eventually pupate within the bag.  Your individual appears to have pupated.

We have had these all over the house since last Autumn. None have emerged as of July. Does anyone know what these are?

Bagworm

Dear Scott,
This is a Bagworm in the family Psychidae.  Caterpillars begin constructing a bag when they first hatch and the material is from the plant upon which they are feeding spun together with silk.  The Bagworm eventually pupates within the bag, sometimes after securing the bag to a surface other than the tree upon which they were feeding.  You must have a host tree or shrub near your stucco wall.

Hello bug man:
I found this at home here in Florida and I have no idea what is it. There’s a lot of them in my bushes and on the walls and they are eating the leaves. They are destroying my bushes. What should I do?

Hi Bugman,
Today I found this
2 1/2″ long cocoon on a cedar tree.  It’s a brilliantly designed and constructed little pinecone-like structure. (It also reminds me of a log cabin.)
Would you please identify it for me?
Thank you,

Bagworm Cocoon

Dear L Welch,
This is the cocoon of a Bagworm, a species of moth in the family Psychidae.  A Bagworm Caterpillar constructs a shelter from silk and bits of the plants upon which it is feeding, enlarging the bag as the caterpillar grows.  The caterpillar never leaves the bag, and eventually pupates inside the bag.  Your Bagworm is in the pupal stage, as it is no longer mobile.

I don’t know what this bug is and I’m dying to find out. My curiosity is killing me. It’s a very tiny bug supporting a huge shell of some kind of wood shavings , if you will. Hoping for an answer!!
