|Emerald Ash Borer|
The EAB beetle is about 10 mm long by 4 mm wide. The adults lay eggs in the crevices of ash tree bark in late May to mid-June. The eggs hatch and the larvae bore under the bark and consumes the cambium of the trees while going through several larval stages. Their random boring pattern cuts across the xylem and phloem of the cambium layer, thus cutting off the transport of water and nutrients which kills the trees. The larva overwinter and then pupate in the spring. Adults emerge from May to July from D-shaped exit holes, with peak emergence in mid-June. The life cycle of the EAB is usually one year, but can be two years in colder climates.
