The legend has it that the "Udumbara flower" blooms once every three thousand years. It usually blossoms at night, with an extremely beautiful fragrance, and wilts by the next morning, just like a passing glimpse of a flower, bringing auspicious and blessed energy. However, according to botanical experts, the "Udumbara flower" discovered in various places across our country is actually a predatory insect —— lacewing. Lacewings generally lay eggs on plants, but under special conditions, they may also lay eggs on other objects such as wood, glass, or metal.
