What is the emergence pattern of the black locust seed moth?
The emergence pattern of the black locust seed moth is: 2 generations per year, overwintering as larvae inside the damaged seed pods. In mid-June of the following year, they emerge as adults, and eggs are laid on the edges of the pods. Newly hatched larvae often feed inside the dried calyx on the stalk of the seed pod, then bore into the pod to damage the tender seeds. After maturing, they spin silk and pupate inside the pod; the pupal stage lasts 7 days. After the adults emerge, they continue to lay eggs and hatch, and the second-generation larvae cause damage until after autumn, then spin grayish-white small cocoons inside the pods to overwinter.
