During the summer we buy almost all of our produce at the weekly farmers market. We do this for many reasons, but mostly because everything tastes so much better. Corn in particular is stellar (though given that we live in Indiana that probably goes without saying).
When I was shucking the corn from this week's trip to the market I found another little critter that seemed to enjoy eating the corn as much as we do (click for bigger pic):
It's called a Corn Earworm (aka Helicoverpa zea). This is just the larva - eventually this little guy will grow into a large moth.
