Millions of fireflies making whoopee in a dense Japanese bamboo forest during the 2019 mating season, captured by Russian photographer Daniel Kordan, who sez of the sexy swarm, in which males produce flashes of light and females respond in kind:

Fireflies are very sensitive. They need clean water nearby, warm humid air (but not rain), and no lights. Not a single photo can show how beautiful it is—shimmering and blinking forest full of little stars.

Behold: a spectacular display of mammatus (breast-like) clouds over Mount Rushmore last September. To wit:

Unlike normal flat-bottomed clouds which form when moist and calm air plateaus rise and cool, bumpy mammatus clouds form as icy and turbulent air pockets sink and heat up. Such turbulent air is frequently accompanied by a thunderstorm. Each mammatus lobe spans about one kilometre. The greater mountain is known to native Lakota Sioux as Six Grandfathers, deities responsible for the directions north, south, east, west, up, and down.
