In spring and summer, emerald ash borer (EAB) larvae pupate in cells chewed by mature larvae in the outer sapwood or bark of ash trees.  This photo shows gradual maturation of EAB pupae to the adult stage by holding J-larvae or prepae, dissected from infested ash trees, in Petri dishes.  This process takes about a month.
