If you look carefully to the left

If you look carefully to the left of the button, you'll see some bristles,
typical of carpet beetle larvae. Frass is not always exactly the color of what
they may be feeding on.

You are correct - carpet beetle larvae did this.

Hi Nancy,
Do you know approximately how old the button is? Casein, a milk protein,
was used to make buttons in the early 20th century. I am guessing that
casein might be vulnerable to dermestid attack as well as horn.
