Eye of the beetle: How the Emerald Ash Borer sees may be key to stopping it

This iridescent jewel beetle, responsible for the death of more than 50 million ash trees in the United States, has blazed an absolute path of destruction west since its discovery in Michigan in 2002. Recently the pest has been detected in Colorado, and just this spring it was confirmed in Nebraska and Texas. Researchers have been doing more than just watching the migration patterns -- they've been studying the creature in hopes of helping to slow it.
