They are poisonous to predators due to toxins they sequestered from plants on which they fed as caterpillars. Adult males spend the mornings patrolling along the courses of forest streams and rivers. They are territorial and chase any rivals. Morphos typically live alone, excluding in the mating season.
The refractive properties of the scales on the wings has been studied as a model in the development of biomimetic fabrics, dye-free paints, and anticounterfeit technology used in currency. A brief bit of internet wisdom about refraction.
The microscopic scales covering the morphos wings reflect incident light repeatedly at successive layers, leading to interference effects that depend on both wavelength and angle of incidence/observance. Thus, the colours appear to vary with viewing angle, but they are actually surprisingly uniform, perhaps due to the tetrahedral (diamond-like) structural arrangement of the scales or diffraction from overlying cell layers. The wide-angle blue reflection property can be explained by exploring the nanostructures in the scales of the morpho butterfly wings. These optically active structures integrate three design principles leading to the wide-angle reflection: alternative lamellae layers, Christmas tree-like shape, and zigzag pattern of the ridges.
The reflection spectrum is found to be broad (about 90 nm) for alternating layers and can be controlled by varying the design pattern. The Christmas tree-like pattern helps to reduce the directionality of the reflectance by creating an impedance matching for blue wavelengths. In addition, the zigzag pattern of ridges destroys the unwanted interference for other wavelengths in wide angle. Morphos secrete a dark oil from their abdomens, which leaches out over the years and stains the wings.
To prevent this spoiling the amazing colouring, the abdomen has been removed. The butterfly has been expertly prepared by hand to museum standards, and is mounted on conservation-grade foam in a hand-made, beautifully crafted case backed with Italian decorative paper. Absolutely ideal for wedding presents, Christmas and birthday presents, home decoration. If you have any queries, or would like to request a different specimen, please get in touch!
None of the butterflies offered for sale are listed on Annex A of the EU Wildlife Trade Regulations, and all are farmed this ensures that not only are the specimens in perfect condition, but that the practice is completely sustainable. Butterfly farming allows farmers to generate income while conserving their natural heritage.The item "Morpho menelaus Real Taxidermy Butterfly in Handmade Museum Quality Frame" is in sale since Saturday, August 24, 2019.
