Many people in many cultures eat insects and use them in medicines. Some bugs are even considered delicacies! Are the poor in Snowpiercer and Bad Blade Runner Remakes all non-minority-Americans?

I made Ant Granola one time when I found that our house's 1/2 gallon of honey had become the amber tomb of a couple hundred or so sugar-crazed ants. Oh the controversy that inspired!

An anthropology study I once read told the story of eating a specific live tree grub in South America. The indigenous would always hide this food from the western anthropologist, bcz they knew urban folk were grossed out by bowls of live white slug-like worms on their tables. One day the majority of the village left on a hunting trip and the intrepid anthro insistently asked an old man to let him try some. The old man took him a short distance from the village into the jungle, smacked open rotting tree with his cane, revealing a mass of wriggling white grubs. The anthro dropped to his knees, took a grub off the tree with his fingers, and ... ate it.

He said it was amazing, tasted like a cross between banana, mango and coconut, with some other delicate flavors in there. Totally worth it.

Star Wars: Return of the Jedi - Gross character Jabba the Hutt eats some live bug-fish kept in a bowl of water, which is meant to be disgusting. (Although where they get bug-fish on the desert planet of Tattooine I don't know.)

Also, Americans already eat bugs: Shrimp, Crab, Lobster, Crayfish are all arthropods... same as beetles. They are just sea bugs.
Shellfish, while not technically bugs, are pretty similar in some ways... especially raw oysters.
The French eat periwinkles (seashore snails) which are great on bread with butter, and famously, escargot, which is available in the US of course.
Caviar is sorta bug-like in some ways.
Squid, Cuttlefish, and Octopus are mollusks... cousins of slugs and snails.
Dry-fried and chili'd crickets are a bar staple in Mexico and Central America. Also whole scorpion-infused Mescal.

@2 he's a crime boss. He imports that stuff.

@4- Good point.
