5449376 Adult(s) Emerald ash borer adults chew D-shaped emergence holes to exit from ash trees.
5449377 Egg(s) The eggs of emerald ash borer are laid on ash trees in bark crevices or between bark layers.  The eggs are white when first laid, but soon turn an amber color.

5449379 Pupa(e) 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. 
5449380 Adult(s) Emerald ash borer adult feeding on an ash leaf.
5449381 Egg(s) Eggs of emerald ash borer are ~1mm in diamater and amber in color.  Females lay their eggs on ash trees in bark crevices and between layers of bark.  To find eggs in the field, we use a sharp knife to separated bark layers, exposing the eggs,
5449384 Damage This photo was taken in the summer of 2011 showing ash trees killed by emerald ash borer (EAB) in a woodlot on the Michigan State University campus.  This is a typcial scene across much of southern Lower Michigan where ash trees were abundant and EAB spread throughout the state.
5449382 Larva(e) Mature fourth-instar larvae or "J-larvae" of emerald ash borer (EAB) in pupation cells in the outer sapwood of an ash tree.   For EAB with a one-year life cycle, J-larvae are found in fall, winter, and early in the outer sapwood or outer bark.
