Once introduced into the hive, the fertilized female of the wax moth begins to lay between 300 and 1,000 whitish eggs, each about 0.1 mm in size, grouped in clusters. Very small caterpillars emerge from these eggs after 5–15 days, provided the temperature exceeds approximately 9 °C. Depending on thermal conditions, the eggs or the larvae at the pre-pupal stage may either overwinter for several weeks or months, or pupate and give rise to moths within a few days. Adult females are fertilized by males outside the hive, and the cycle can begin again.
