Might be one in the same. From Wikipedia: Phereoeca uterella is a species of moth<https://en.wikipedia.org/wiki/Moth> belonging to the family Tineidae<https://en.wikipedia.org/wiki/Tineidae>. It is commonly known as the plaster bagworm but as the term "bagworm" more properly refers to moths of a different family (Psychidae<https://en.wikipedia.org/wiki/Psychidae>), it is often called the household casebearer – which may in turn refer to the related Phereoeca allutella<https://en.wikipedia.org/wiki/Phereoeca_allutella>. It is found in warm, humid climates throughout the Americas<https://en.wikipedia.org/wiki/Americas>although the exact range is difficult to map as it is easily confused with other case-bearing tineids.

Tony, the photos may be of a plaster worm, which is fairly common in the south, since it was hanging from the ceiling.

Hi James These appear to be cocoons of Phereoeca uterella, the Household Casebearer Moth. The caterpillars generally feed on silk (of spiders or other moth cocoons), but they also feed on wool and hair, so can be a pest in some collections. It's possible they are doing no damage, but clearly it would be prudent to check all susceptible objects. The cocoons are fairly obvious, so any infestation should be readily spotted.

They have appeared before around this time of the year. Should I be concerned for the objects in the area? Location is Charleston, SC and sorry for the blurry pictures. I will never judge any of you ever again.
