How does the emerald ash borer reproduce?

The emerald ash borer (EAB) reproduces through a lifecycle that includes egg, larval, pupal, and adult stages. Adult females lay their eggs in the bark of ash trees, often in small groups. Once the eggs hatch, the larvae burrow into the tree's bark and feed on the inner bark and cambium, disrupting the tree's nutrient transport. This feeding can lead to the tree's decline and eventual death, facilitating the cycle of reproduction as adults emerge from the tree to lay new eggs.
