Why Are They Called Carpet Beetles

I am not sure of all the reasons why they are called carpet beetles, but this photo gives us a hint.

This is not a photo of a lunar landscape.  This is the carpet inside of someone's closet on the UES.  The carpet beetles went unnoticed for quite sometime, and by the time we finally dug in and pulled out the shoe boxes this is what we found.  And this is just one photo of dozens where the beetles, specifically the beetle larvae, had eaten completely through the carpet down to the padding underneath and in some cases even to the floor.  Apparently the larvae can exist in their state from 1-3 years, and that is plenty of time for them to cause serious damage such as what you see above.
