What is the primary stage of the box tree moth responsible for destroying boxwood foliage?

The larval stage (caterpillar)

The destruction associated with the box tree moth is entirely caused by the larval stage, which are voracious eaters of boxwood leaves. Adult moths serve primarily as dispersers and cause no direct damage to foliage.
