Posts Tagged ‘Wooly Alder Aphids’

“All the leaves are brown, and the sky is gray…I’ve been for a walk, on a winter’s day.” California Dreaming by The Mammas and the Pappas has been playing in my head a lot lately; maybe because I hoped to do one more fall foliage post. But now, since all the leaves are brown I doubt that it will happen.

I shouldn’t say all the leaves are brown because bracken fern’s leaves (Pteridium aquilinum) have turned kind of a pinky gray. Bracken is one of the oldest ferns; fossils date it to over 55 million years ago, so it has been very successful. That might be because it eliminates competition by releasing chemicals that inhibit the growth of other plants. That’s why large colonies of nothing but bracken fern are seen, often along roadsides. Some Native American tribes peeled and cooked the roots of bracken fern to use as food but science has shown that all parts of the plant contain carcinogens.

It has gotten cold here all of the sudden; cold enough to be record breaking in parts of the state, so scenes like this one of frosty leaves and grass have become commonplace in the morning. I was hoping I could get all of the leaves picked up before it snowed, but that isn’t going to happen.

This juniper haircap moss (Polytrichum juniperinum) was about as frosty as it could be but mosses can handle extremes and this little plot of moss should come through winter completely unscathed.

The thin, crinkly white puddle ice that I used to love riding my bike through as a boy has appeared on the puddles. I was never thrilled to see it in the fall but I loved seeing it in the spring because it meant that the earth was warming up after a long winter and soon school would be letting out for the summer. I’ve learned since then that the white color comes from bubbles, because this ice contains lots of oxygen. I’ve also learned that you can see some amazing things in this ice; I’ve seen wave ripples, birds flying, high mountains, distant stars, and space and time. All of that and more can all be there for the seeing, but most of us don’t take the time to look.

At the river there was ice of another kind. Just seeing it in a photo makes me shiver because I remember how cold it was that day.

Speaking of the river, the Ashuelot’s banks won’t hold much more. We’ve been getting 1-4 inches of rain each week since about mid-July and so far there hasn’t been any serious flooding but as this photo shows, something is going to have to give soon if it keeps up. Luckily the weather people are finally talking about a pattern change, and except for a few snow showers the upcoming week looks fairly dry for the most part.

Of course streams are running furiously as well. I visited Beaver Brook in Keene recently to admire the stone wall that was built over and around the brook, probably well over a hundred years ago. It’s the only stone wall built around a brook that I’ve ever seen; essentially a box culvert on top of rather than below ground, built by a clever farmer I’d guess. The only time you can get a good look at it is after the leaves fall.

Even beavers are saying “enough rain already!” This beaver dam was breached by high water because apparently even the industrious beavers can’t keep up.

Beavers have been very active near my house. They cut down this 5 inch diameter poplar tree and I was surprised because in the past they’ve always cut birches first. There are quite a few birches in the same area but so far they’ve left them alone. They can cut and drag off an amazing number of trees in one night.

Usually it’s the top branches of a tree that beavers want most for winter food so I was surprised that they left this poplar limb behind. I’m guessing that they probably came back for it that night.

Though jelly fungi grow at all times of year I think of them as winter fungi because that’s usually when I find them. I often see them on fallen branches, often oak or alder, and I always wonder how they got way up in the tree tops. Yellow jellies (Tremella mesenterica) like this one are called witches butter and are fairly common. We also have black, white, red, orange and amber jelly fungi and I’d have to say that white and red are the rarest. I think I’ve seen each color only two or three times. Jelly fungi can be parasitic on other fungi.

The most common of all jelly fungi is the amber one in my experience (Exidia recisa,) because I see it all the time, especially after a rain. This one always reminds me of jellied cranberry sauce. Jelly fungi dry out when it’s dry and appear as tiny colored flakes that you’d hardly believe could grow as much as they do, but they absorb water like a sponge and can grow to 60 times bigger than they were when dry. Jelly fungi have a shiny side and a kind of matte finish side and their spores are produced on their shiny sides. After a good rain look closely at those fallen limbs, big or small, and you’re sure to find jelly fungi.

Hemlock varnish shelf fungi (Ganoderma tsugae) can be quite big but they are still easiest to see when the leaves fall. Their color can vary greatly but they’re almost always shiny on top, hence the “varnish” part of the common name, but this example had no shine. In China this mushroom is called the Reishi mushroom and it has been used medicinally for centuries. It is considered the most important of all the herbs and substances used in Chinese medicine and scientists from around the world are researching its anti-cancer potential.

When I started my current job I saw a tree / shrub that I hadn’t ever seen. I watched it for a while to see what it would do but even after watching it for months I couldn’t find it in any guide, so I put it on the blog as an unknown. Right off my blogging friend Clare from the Suffolk Lane blog told me it was a spindle berry, native to Europe,  and after researching it I was happy with that name and I’ve called it that ever since. But recently I found out that we have a native version called eastern wahoo (Euonymus atropurpureus,) so now I’m going to have to watch it even more closely to see which one it is. I think it’s probably the native version. The photo above is of its interesting bright red fruit.

In my last post I mentioned how the inner bark of staghorn sumac (Rhus typhina) was often a beautiful bright red, but the odd thing about it is that it seems to turn red only after exposure to the elements. I’ve peeled the bark from dead staghorn sumacs and have never been able to find any red color, but if I look closely at dead sumacs with bark that has peeled naturally like that in the above photo, it’s often quite red. How and why it changes is a mystery to me but it’s nice to see in winter when there isn’t a lot of color.

Wooly alder aphids (Paraprociphilus tessellatus) are sucking insects that pierce the bark of an alder and suck out the sap, so they do harm the plant. They can be winged or unwinged and need both alders and silver maples to complete their life cycle. Eggs overwinter in crevices in the bark of silver maple trees. In spring the nymphs hatch and begin feeding on the undersides of new leaves until in late May through July they develop wings and fly off to find alders. Once on an alder they begin feeding on the sap and reproducing. Soon the colony is made up of aphids in all stages of growth and becomes covered in a fluffy white, waxy “wool” like that seen in this photo. Some aphids mature and fly off to silver maples to mate and once mated the female will lay a single egg in a crevice in the bark and the cycle will repeat.

Last year I was able to do an entire flower post in November but this year it got cold quickly, so I was surprised to see this little lobelia (Lobelia inflata) still blooming. The flowers are no bigger than a pencil eraser and its common name of Indian tobacco comes from its inflated seedpods, which are said to look like the pouches that Native Americans carried their smoking mixtures in.

I’ve seen native witch hazel (Hamamelis virginiana) bloom in January in a warm winter, so it wasn’t a surprise to see it blooming in November, but even witch hazel can have too much cold and I doubt I’ll see these pretty blooms again until the spring witch hazels bloom in March. It’s an event I’ll be impatiently waiting for. Just the thought of spring, my favorite season, is like a soothing balm that gets me through winter.

If you see no reason for giving thanks, the fault lies only in yourself. ~Tecumseh, Shawnee

I hope everyone has a safe and happy Thanksgiving! Thanks for coming by.
