The invasive emerald ash borer is rearing its head and fluttering its wings earlier than ever thanks to Indiana's mild winter.

Warmer than normal weather has given the tiny Asian beetle extra time to lay larvae that burrow into ash trees and suck its tissue dry until death, a Purdue University entomologist says.

"They will fly now and into the end of July," professor Cliff Sadof explained. "The adults will feed on leaves for a couple weeks, mature, mate, and lay eggs. You can't wait too long to put the insecticides in the soil or on the trees. It is a good idea to do it earlier than later."
