Life cycle of emerald ash borer in Life cycle of emerald ash borer in Northeastern US & CanadaNortheastern US & Canada

Adults are active from late May to mid-August. Each adult lives 3-4 weeks. Beetles feed on ash foliage.

Adults mate; female lays single eggs on or just under bark. Usually 60-90 eggs per female but can range from 2 to 258 eggs.

Larvae bore through bark in July & feed aggressively in serpentine galleries in the

cambium in August and September.

Extensive galleries under bark disrupt translocation of water & nutrients in the tree

Extensive tunneling causes canopy dieback and eventually…

Death of the tree except for sprouting from the lower trunk.

Larvae spend the winter under the bark and pupate in the spring

Pupal development & emergence the Pupal development & emergence the following spring. Adults emerge from trunks following spring. Adults emerge from trunks

from late May to early Augustfrom late May to early August

When adults emerge they leave a

‘D’-shaped hole about 3/8” wide
