What's That Bug? does not endorse extermination

Hello-
I have these very strange bug/cocoon things hanging all over the outside of my house, and they are on the inside of the porch. The just appear to hang there, and occasionally they must move, but I have never seen them move. I have attached several pictures of them on the porch. We live in South Florida and they are here all year. Any input would be appreciated.
Best Regards,
Daniel Foster

Dear Daniel,
Sorry for the delay in answering. You have a type of Casebearer, Family Coleophoridae. This is a type of moth which forms a case in the larval stage and pupation occurs in the case. They are often pests on apple and other fruit trees.

4 Responses to Cocoon Bugs are Case Bearing Moth Larvae

    Recently, Daniel Foster wrote you a description of what you thought to be a case bearing moth. They live in south Florida. We live in Northern California and we have similar casings, however, they are rectangular in shape and looks like they have tiny legs surrounding the bottom and look spinny, almost prehistoric. Have any ideas?

      Without a photo it is difficult to be certain. Depending upon the building materials, cases in different areas might exhibit variations. Also, we would not overrule Carpet Beetle Larvae based on your description.

    Another South Floridian here. These cocoons are ubiquitous in our area – and after almost 30 years of life, I finally saw one move for the first time just now! Hooray!

    Thanks for the identification, Bugman.

      Wow, you found one of the oldest postings on our site of a Casebearing Moth Larva. We must have posted nearly a hundred newer ones since then.
