A butterfly is an insect of the order Lepidoptera. Like all Lepidoptera, butterflies are notable for their unusual life cycle with a larval caterpillar stage, an inactive pupal stage, and a spectacular metamorphosis into a familiar and colourful winged adult form. A monarch butterfly is is a milkweed butterfly, perhaps the best known of all North American butterflies.

Part of a striped muscle fiber of a water beetle prepared with absolute alcohol. Labels: A, sarcolemma; B, Krause's membrane. The sarcolemma shows regular bulgings. Above and below Krause's membrane are seen the transparent "lateral discs". The chief mass of a muscular compartment is occupied by the contractile disc composed of sarcous elements. The substance of the individual sarcous elements has collected more at the extremity than in the center: hence this latter is ore transparent. The optical effect of this is that the contractile disc appears to posses a "median disc" (Disc of Hensen). Several nuclei of muscle corpuscles, C and D, are shown, and in them a minute network.
