I've eaten toasted mealworms (they had cheese powder on them and tasted like Cheetos, only made of mealworms.) And I've eaten a cricket, inside a Cricket Lick-It lollypop (it tasted kind of like a peanut.) Both of those examples were crunchy and not very nauseating.
However, just the thought of biting into a squishy, insect-guts-filled silkworm pupa makes me want to hurl. So I left these cans of (presumably) delicious pupa on the shelf of the Korean market.
