RACHEL MARTIN, HOST:
Here at NPR, we've been trying to do more stories that answer people's questions about issues they face in their daily lives. NPR's Joe Palca apparently didn't get the memo because he's got a story with the answer to a question almost nobody has - what to feed a colony of captive locusts.
JOE PALCA, BYLINE: To answer that question, it helps to go to Tempe, Ariz.
RICK OVERSON: We are inside one of the two main rooms of the locust lab here at Arizona State University. We affectionately refer to it as Hopper Town.
