Small problem with using this marketing technique in Israel: prawns aren't kosher. Locusts, on the other hand, are - or at least one species of locust is; I don't know whether the current swarm is of the kosher species.
Kosher locusts can be recognised by the Hebrew letter 'chet' on their undersides. Really. I've seen them. (Yes, they come with their own hechsher.) Roast them in an oven, then pull the legs off and eat like popcorn.
