As human food

In cold climates supporting reindeer or caribou -reliant populations, large quantities of Hypoderma tarandi (caribou warble fly) maggots are available to human populations during the butchery of animals.

The sixth episode of season one of the television series Beyond Survival, titled "The Inuit – Survivors of the Future", features survival expert Les Stroud and two Inuit guides hunting caribou on the northern coast of Baffin Island near Pond Inlet, Nunavut, Canada. Upon skinning and butchering of one of the animals, numerous larvae (presumably H. tarandi, although not explicitly stated) are apparent on the inside of the caribou pelt. Stroud and his two Inuit guides eat (albeit somewhat reluctantly) one larva each, with Stroud commenting that the larva "tastes like milk" and was historically commonly consumed by the Inuit.

Copious art dating back to the Pleistocene in Europe confirms their consumption in premodern times, as well.

The Babylonian Talmud Hullin 67b discusses whether the warble fly is kosher.
