A butterfly so unique that it is - really - a tale of its own. If we were to reconstruct the etymology of its scientific name, "heteroptera" would suggest "different wings" (from "hetero" = different and "ptera" = wings) and "morpheus" some sort of modification.
Indeed, the subclass of this colorful creature, the pterigotes (winged insects), includes other insects such as... urgh: bugs (Heteroptera too)! Bugs, too, actually worship plants and have wings for flight that are hidden by other, more armored "wings" that protect them. The lack of this second kind of wings explains the "morpheus", so, to sum up, we ought to be dealing with an insect with "several modified wings". Yeah but, then why do French people call it "le miroir", i. e. "the mirror"? It takes a bit of imagination but it's gonna be fun: let's try imagining some drops of water on a mirrored surface... can you see them? Now, look at our butterfly's wings... bingo! So, this one is part of the family Hesperiidae, the only member of the monotypic genus Heteropterus. The species can be found in isolated populations in Europe and east across the Palearctic to Central Asia and Korea. The length of the forewings is 15-18 mm. The larvae feed on a variety of plant species, including bluegrass. As you can see, the butterfly has a very distinctive and attractive underside, but a gray upper part (which is rarely seen, as it usually settles with its wings closed). The flight is just as distinctive and in fact allows immediate identification of the species: the butterfly looks like bouncing through the air with little sense of direction, almost as if it were drunk.
