Around my house I've been spotting these very small brown/tan spotted bugs:


It moves quite slow, and doesn't seem to fly, only crawl (though it does look like it has wings). It's very small, not much bigger than a sugar ant for comparison.

What is this bug? This is in the Philadelphia region of Pennsylvania.

This is almost certainly one of the Dermestidae, known as skin bugs or carpet beetles. I think this is probably a varied carpet beetle (Anthrenus verbasci) They are a common world-wide pest and the larvae are known to eat a range of mostly animal-derived materials containing keratin or chitins, including things like wool, silk, leather, bone, horn and feathers.

As per comment from @Willeke that this is a common question:

They don't pose a risk to us, but can cause damage to carpets, clothes, books, food stuffs and similar items. If your carpets or blankets are made from wool or other animal product, these are the most common items to be damaged.

The larvae look a lot like a very small hairy caterpillar (photo by André Karwath aka Aka, CC BY-SA 2.5 https://creativecommons.org/licenses/by-sa/2.5, via Wikimedia Commons):
