The Blue Morpho Butterfly, in particular, dazzles all with it’s vivid coloration and metallic sheen. These colours are not a result of pigmentation but rather are an example of iridescence. The colours produced vary with viewing angle but they are actually surprisingly uniform. This is perhaps due to the diamond-like structural arrangement of the scales called “photonic crystal”. All insects and Butterflies vary slightly in size and shape. You will receive a high quality specimen of the selected item but not the exact one pictured.
