Although I will try not to read too much into the Biblical Plague thing—John the Baptist ate them and Locusts are Kosher—Locusts in Mecca are an appropriate metaphor for the criminal empire of the fake prophet that spread from this spot to devour destroy the surrounding civilizations.
(May the pilgrimage of the “faithful” be blessed with a hundred million locusts!)
"Confirmed" by Google. Also, it turns out that locusts are halal. Mohammed is known to have eaten locusts.
When life gives you plagues of locusts, declare them food (or you'll starve to death).
