This is the cochineal beetle:

It eats cactus and if you grind up the females, they turn into a bright red mess. The ground up bug sludge is then sold as a red food coloring called either "cochineal" or "carmine". Check your ingredients on your food. You see it a lot with red colored foods. Yes, you have probably eaten that bug without even realizing it. In fact, it's also commonly used in red lipstick. Red lips just don't seem as sexy when you know it's just a woman with bug guts smeered on her mouth, do they?
Here's another. This is the Lac Bug.

This one is not just in your food, but your furniture as well. The female lac bug secretes a ruddy brown resin. They get ground up along with their secretions, bark, and an alcohol mixture to create what is callled "shellac". This is a common wood finish that creates a reddish brown glow that makes a home feel inviting and warm. People like the color so much that some companies have started to put it in your food too. Certain types of chocolate chips have shellac in them so that they have a nice glistening shine that only bug shit can provide.
