It landed on him before he took the penalty, and flew off shortly afterwards.
How utterly strange.
Is this normal in Brazil? It's terrifying.
Everyone on Twitter's pretty freaked out by it.

(Sadly Rodriguez' penalty was too little too late. Brazil now proceeds to the semifinals after beating Colombia 2-1.)
A Brazlian commenter tells BuzzFeed she thinks the insect is not a locust but rather a type of cricket called an esperanza, otherwise known as a katydid.
