After three snowstorms this past week, the latest dumping over a foot of white stuff in western Maine, winter has finally arrived. Or, as a friend calls it, “Second Winter.”

In fact, there is finally so much snow, that my wee studio, the spot where I used to escape to write and sketch many moons ago, looks as if it’s being gobbled up and about to disappear into the landscape.

I love winter and so I’m thrilled to know that it’s not ready to give up on us yet. I also love how winter likes to play, creating tree boas that defy gravity.

In spite of all that, I do need a touch of color now and then and so I headed to a local brook where I know the Mallards gather.

And tread water as they wait for what, I don’t know. Perhaps for me to admire them: those shiny green heads, the sharp white necklaces, and cute little curly tail feathers. They tolerate our cold winters and as long as there is food and open water, such as this spot, I know where to find them.

I finally left the ducks behind and continued walking beside a second brook, pausing occasionally to reflect on the changes I’ve observed in this spot over the years, including one late November afternoon when I heard the water flowing as if over a fall and then spotted beavers hard a work, building a dam. Today, it was the spring ice that caught my attention and I know that as much as I want winter to last, spring is just around the corner and soon I’ll be peering into vernal pools.

And then, something quite small captured my attention. A Winter Stonefly! Scurrying across the snow.

Suddenly, what began as one sighting turned into two and then . . . hundreds as my eyes focused. In winter, crazy as it may seem, the aquatic immature stage of a Winter Stonefly, aka naiad, crawls from the rocky bottom home of the brook where it has spent the last year or more maturing (going through as many as thirty molts)and shredding falling leaves, climbs up through crevices in the snow that covers the brook, finds a plant or some other spot to emerge as an adult, and leaves behind its shed skin, much like a dragonfly or damselfly.

My attention in tune, I began to notice several things. First, there were large Winter Stoneflies . . .

and some much smaller, known as Small Winter Stoneflies in common terms. Their wings are non-functional, thus they crawl. But herein was the curious thing, at least to me. They all were headed west.

It didn’t seem to matter if I found them where the brook was to the east, or to the north, all of the Stoneflies walked in a westerly direction. Why?

I began to wonder where they were headed, so . . . I followed them. To tree trunks. I’d say any tree trunk, for the species didn’t seem to matter, but maturity did and they all headed to older trees. At least, the insects I observed.

This Small Winter Stonefly had obstacles of ice crystals to work around, but it was on a mission to reach that tree.

Mission accomplished.

Once there, the insects crawled down under the snow beside the trunk and I had to wonder if a party was in the making. The bark is warmest in that spot, so it was a good place to get out of the weather.

Stoneflies have hammer-like structures on their abdomen that make noise when thumped against a surface, like a tree trunk or a twig or even the ground. This is a mating call. The males drum, and the females drum back, and voila, they find each other and canoodle.

It’s not the same drumming sound as we hear daily from our resident Pileated Woodpecker. In fact, it’s made for Stonefly ears only and it’s not a party for which we receive an invitation.

Seeing so many Stoneflies made me want to celebrate anyway for they, like Mayflies, and Caddisflies, are particularly sensitive to pollution and serve as bioindicators of water quality. That means the brooks beside which I walked have excellent water quality.

And though I couldn’t hear the percussion instruments at the base of the trees, I am grateful to have spent some time with those who march to the beat of a different drummer.
