Scientists have discovered two new species of butterflies in eastern USA—"an extremely rare discovery." That's cool, but I just wanted to tell you that butterflies have penises, which is one of the reasons that served biologists to identify them as new species. They look like deathly alien manta rays.
The new Intricate Satyr (Hermeuptychia intricate — A) compared to the well known Carolina Satyr (Hermeuptychia sosybius — B). On the right, another new species: the South Texas Satyr.
