Here’s a nice, close-up picture of a mourning cloak butterfly. We haven’t seen many of them in recent years, but perhaps they’re making a comeback? They mostly look black to the naked eye, but when the morning sun is backlighting them you can see the rust-colored wings and the pale blue spots along the edges.
