Yup, typo. Apparently inago are actually locusts, so we were both wrong about the species :)
FWIW, I've also tried beondegi in Korea, and I agree with you. It was easily the least pleasant of the insects I've tried (locust, cricket, peanut worm, silkworm).
Locusts are actually just various species of grasshopper. When there's abundance after a period of hard times, some some grasshopper species transform into locusts, turn from green into yellow, grow their wings and start swarming. The solitary and gregarious phase. When one locust becomes gregarious, he'll touch other locusts to turn them gregarious too.
