This is it I The representation of the beginnings of The Chaos Theory (the famous 'Butterfly Effect'). This is a close up of a butterfly wing. A butterfly has four wings, two forewings and two hindwings and they are a fascinating construction; Butterfly wings are made of two chitonous layers (membranes) that are nourished and supported by tubular veins. The veins also function in oxygen exchange ("breathing"). Covering the wings are thousands of colorful scales, together with many hairs (setae). The name Lepidoptera (which includes butterflies and moths) means "scale wing" in Greek. These wing scales are tiny overlapping pieces of chitin on a butterfly or moth wing. The scales are outgrowths of the body wall and are modified, plate-like setae (hairs). The front and back of the wings usually have different patterns. It is a joy to watch butterflies and with the hurricanes we have had lately, we should probably watch them closer....
