Specimen of a butterfly.
It is reported that a total of 9 "flash butterfly" specimens were exhibited in this special exhibition. "Flash butterfly", also known as "flash butterfly", "Moore floating butterfly", etc., living in the tropical rainforest of South America, the wings are huge, can quickly soar in the sky, difficult to catch, the wings shine with blue, green or purple metallic luster, see them, people will have a real and illusory feeling.
The eggs of the butterfly are hemispherical in shape, like small buns, and the adults are huge. The most attractive thing is the brilliant metallic luster on the wings of the glittering butterfly. The scales of the butterfly are structurally more complex, and their subtle structure is composed of multi-layer three-dimensional fences, similar to shutters, except that their structure is far more complex than shutters. When light hits the wings, physical phenomena such as refraction, reflection and diffraction occur, so the complex structures on the wings of the butterfly produce a rainbow of brilliant colors under the action of optics. When a flock of butterflies flutters in the rainforest, it shines with a metallic luster of blue, green, and purple, and the "blue phantom" is created.
