This post series opened with Part 1, an exploration of some snow-dwelling lifeforms.
The sun sets on the Yukon Territory’s Porcupine River, slowly melting into a far-off, lazy oxbow, pouring its tangerine light one last time over the endless, icy stillness. It’s just before four in the afternoon, the New Year is soon approaching, and it is cold. Very, very cold. As the blue above dims, and the blinding mango creamsicle spectacle comes to a rapid close in the west, you can almost hear the river ice creak and wince in anticipation for what’s coming. It only got up to 20 below today. The nights have grown large this time of year, and cruel. First light won’t come for what seems like eternity, and by then, the air will be a devastating -60 degrees Fahrenheit. Cold enough to kill exposed human skin in a handful of minutes. Cold enough to turn even antifreeze-laden gasoline into flammable slush. Cold enough for breath to stiffen in an instant, collecting as a growing layer of biting rime on every hair on one’s own face; eyelashes, eyebrows, the whole bit. In the growing dark, nothing moves. Chickadees settle into tree cavities, and rapidly begin burning through the fat reserves they gained during the day’s feeding, all just to keep warm. Caribou huddle and lay low. Ptarmigan wriggle into the snow (surprisingly, for insulation), stoking their metabolic fires with a crop pouch full of food. To survive the night, Life winds down everywhere, becoming motionless and dipping unnervingly near death in a desperate attempt to stay alive.
Well, everywhere except within the cramped, moist layers of bark of the naked balsam poplars lining the riverbank, stony and brittle with the cold. In there, somehow, life stirs, pushing and wriggling its way through its frozen, wooden den. It’s a tiny beetle grub, a larva of the northern red flat bark beetle (Cucujus clavipes puniceus), no longer than the graphite tip of a well-sharpened pencil. It has no blanket of thick fur or fluffy feathers, no fat-powered metabolic oven to keep it warm. It is a bare-assed worm, twenty feet up in a barren, ligneous spire, sandwiched between the unrelenting sadism of the Arctic atmosphere and a block of nearly lifeless wood….possibly the worst possible location for cold exposure. And yet, it is comfortable, its teeny body barely noticing the silent, breath-stealing chill invading from outside the bark.
Why? Because when the frosty grip of boreal death extends its hand, the larval red flat bark beetle tells it to fuck off.

Not bad for something that looks like a condom filled with urine-flavored Jello.
