Posts Tagged ‘Hoverflies’

Last Saturday more showers and thunderstorms were in the forecast so I didn’t want to be exploring any mountaintops. Instead I went to Beaver Brook Natural Area in Keene, where I knew there would be plenty of interesting things to see.

Beaver Brook itself was high. With hurricane Henri supposed to pay us a visit over the coming days I was hoping to see lower water levels, because we had so much rain through July there simply isn’t anyplace left for the water to go. I met an old timer up here once who said he had seen the water come up over the road years ago, but I’m hoping I never see that. Keene would be in real trouble if this brook got that high now.

NOTE: Henri came and went while I was putting this post together and though there was rain, thankfully there was no serious flooding in this region.  

I thought I might see blue stemmed goldenrod (Solidago caesia) blooming but no, it’s going to wait a while, apparently. Its stems usually grow vertically until the flowers begin to open and then they fall over into a more horizontal position, but these had already fallen. Its yellow blooms grow in tufts all along the stem so it’s an unusual goldenrod. It isn’t considered rare but I know of only one or two places where it grows. It is also called wreath goldenrod.

There are also lots of white wood asters (Aster divaricatus) here. They are fairly common at this time of year but they start blooming in August, so by first frost most of them have already finished.

Lots of jewelweed (Impatiens capensis) grows here too, all along the old road, and most of the plants were blooming heavily. This plant had flowers in pairs, which I don’t usually see.

This one had its legs crossed, and that’s something I’ve never seen before. How strange. It’s as if it wanted to close off the access to its nectar. This plant typically blossoms right up until a frost but as day length shortens the plants will produce smaller, closed flowers with no petals and no nectar. They self-pollinate and their sole purpose is to produce plenty of seeds.

Smoky eye boulder lichen (Porpidia albocaerulescens) is one of the most beautiful lichens that I’ve seen and it does well here on the ledges. The beautiful blue / turquoise spore producing apothecia against the golden color of the body (thallus) are very striking. But light has everything to do with it; the way it reflects off the waxy coating on the apothecia are what turns them blue. Come here when the lichen is in the shade and they’ll be a smoky gray.

I don’t visit the lichens and mosses that grow on these ledges quite as freely as I once did, and this is why. This ledge collapsed a couple of years ago but more stone has fallen since. The trees above are being undercut now so they’ll fall one day as well. All along this old road if you look carefully, you’ll see seams of fractured and crumbling soft stone which is usually feldspar, running through the ledge faces. I stay away from them now for the most part. Any fallen stone in this photo is easily big enough to crush a person. It must have been a mighty roar.

One of the best examples of a frost crack I know of is on a golden birch that lives next to the brook here, and I wanted to get a photo of it. Much to my surprise the spot where I used to stand to get photos of it is now in the brook, so I was teetering on the edge when I took this one. Frost cracks happen when the sun warms the tree and the cells just under the bark expand. If nighttime temperatures are cold enough the bark will cool and contract rapidly, quicker than the wood underneath, and this stress on the bark can cause it to crack. I like this one because of the difference in color between the bark of the tree and the healing crack. It stands out beautifully and if you happen to be trying to explain frost cracks, that’s what you want.

I tried not to look down while I was hanging onto a tree with one arm and taking photos of the frost crack with the other, but since I had the camera out anyway…

While most other maples have dropped their seeds, mountain maple seeds (Acer spicatum) haven’t ripened yet. There are quite a few of these trees here but this is one of only two places I’ve seen them. At a glance the big leaves look much like striped maple leaves (Acer pensylvanicum.)

The sky was all sun and clouds and it was beautiful here. The no passing lines still on the abandoned road always seem kind of ironic to me because the only thing passing here now is time. To think my father and I used to drive through here when I was a boy. Of course the trees and undergrowth didn’t come right up to the road edge then though, so it must have seemed a much wider corridor. I can’t really remember much about it. Some people say the road was abandoned when the new Route 9 was built in the 60s and some say it was in the very early 70s but I’ve never been able to get a solid date, even from the highway department.

I was finally able to get both the leaves and flowers of big leaf aster in the same shot. The flower stalks rise about 2 feet above the leaves so you have to know a little about depth of field for a shot like this. I’m noticing more and more that these flowers are purple, when just a few years ago almost all of them I saw were white.

I’m not seeing the number of blackberries that I used to, and what I do see seem smaller now. This one looked more like a black raspberry though the canes I saw certainly were blackberry. In a tangle like this maybe there was a cane or two of black raspberry here. Maybe the birds are getting to the berries before I see them.

The strangest thing I saw here on this day was a bunch of what I think are hoverflies swarming all over a white avens (Geum canadense) flower. According to Wikipedia these small flies are also called flower flies and the adults of many species feed on nectar and pollen. They looked to be going for the anthers, which would mean pollen.

This pretty view reminded me of my father, who loved to fish for brook trout. He tried to get me interested but I cared more about exploring the woods than fishing when I was a boy. I don’t think there were too many father and son fishing trips before he realized that he could fish or he could chase after me, but he couldn’t do both. At least, not at the same time. It worked out though; I got to roam the woods nearer home and he got to fish in peace.

Orange crust fungus (Stereum complicatum) covered a log. It’s a beautiful fungus that is bright enough to be seen from quite a distance. It loves moisture but dries out within a day or two after a rain.

Artist’s conks (Ganoderma applanatum) grew on another log. This bracket fungus gets its name from its smooth white underside, which is perfect for drawing on. Any scratch made on the pure white surface becomes brown and will last for many years. I drew a farm scene on one a long time ago and I still have it. Artist’s conks are perennial fungi that get bigger each year. Older examples can be up to two feet across but these were young and not very big.

Eyelash fungi (Scutellinia scutellata) grew on a rotten birch log that was absolutely saturated with rain water, and that’s just the kind of wet wood environment that they like. This fungus gets its common name from the eyelash like hairs that grow around its rim. They can be hard to see so you have to look closely. Sometimes the “lashes” curl inward toward the center as you can see happening on the example to the right of the largest one, so another common name is Molly eye-winker. As fungi go, they are quite small. None of these examples had reached pea size.

From the road these Jack in the pulpit berries (Arisaema triphyllum) looked bright red to me but when I got closer, I saw they hadn’t ripened yet. That’s part of being colorblind, but it was okay because these berries are what led me to the log with the eyelash fungi on it. They’re so small I never would have seen them from the road.

The berries of false Solomon’s seal (Maianthemum racemosum) weren’t ripe yet either. Once they turn fully red they’ll disappear very quickly, and that’s why you rarely see ripe ones on this blog. I’ve heard they taste like treacle but I’ve never tried them. Actually I’ve never tasted treacle either, which in this country is called blackstrap molasses.

The place that gets the most sunlight here is the clear space over the road, so of course all the trees and plants lean toward that light. It doesn’t help that they also grow on hillsides as well along much of the roadway. That’s why I see fallen trees almost every time I come here. They often fall on the electric lines that you might have seen in some of these photos.

I finally made it to Beaver Brook Falls but all I can give you is a side view because I didn’t dare climb down the steep, slippery embankment. I say “finally” made it because, though the walk to the falls from the start of the trail is just 7 tenths of mile it usually takes me two hours or more, and that’s because there is so much nature packed into what is really a relatively small space. For someone who likes to study and truly learn from nature, it doesn’t get any better than this amazing place.

One of the hardest lessons we have to learn in this life, and one that many persons never learn, is to see the divine, the celestial, the pure, in the common, the near at hand – to see that heaven lies about us here in this world. ~John Burroughs
