Posts Tagged ‘Azalea Gall’

An eastern cottontail hiding in the tall grass saw me as soon as I saw it and we both froze. I was able to turn my camera on and slowly raise it up to eye level, and finally get a couple of not so hot shots.

The rabbit was fine with me being there for a while because it munched on grass, but then it turned and hopped off, and I saw its fluffy cotton tail.

What I believe is a band winged meadowhawk dragonfly landed on an old garage door at work early one morning. The light was low and the photos weren’t that good so I was going to discard them, but then I saw something odd going on. This dragonfly had what appeared to be tiny eggs all over it.

Here is a closer look at the “eggs” on the dragonfly. I’ve searched for dragonfly diseases and dragonfly parasites but have had no luck finding anything out. If you happen to know what this is about I’d really love to hear from you. I know dragonflies lay eggs but I’ve never heard of them laying them on each other.

Note: A helpful reader has identified these as immature water mites. What is happening in these photos is called “Phoresy,” which a symbiotic relationship where one organism transports another organism of a different species. The red mites are parasites in the tick family and they do suck the dragonfly’s bodily fluids. When the dragonfly lands or hovers near water they will fall / jump off. Thanks go to Ginger Wells Kay, to the folks at BugGuide.net and to Kathy Keatley Garvey and the bug squad from the University of California for this information.  

This dragonfly looked fine but I haven’t been able to identify it. One of the club tails, maybe?

A grasshopper seemed very interested in what I was doing. In fact as I was taking its photo it turned to get a better look. Or maybe to give me a better look.

I expect to see leaves in colors other than green in the spring or fall but not in summer, so these ash leaves seemed confused to me. It is thought that plants might do this to prevent the leaves getting too much sunlight, but it doesn’t seem like anyone really knows for sure.

I can’t explain why some plants do this but it can often be beautiful, as this Joe Pye weed shows.

For years now I’ve meant to check our native alder bushes in the spring for new tongue gall growth and each year I’ve forgotten. But then I was taking photos of a Deptford pink that grew under an alder and I stood up and there they were. And they really do look like tongues, especially at this stage. Some were even bright red.

I went back on a rainy day and got this shot of another tongue like gall. Instead of being caused by an insect like many galls, alder (Alnus incana) tongue gall is caused by a fungus (Taphrina alni.) The fungus chemically deforms parts of the ovarian tissue of the female cone-like catkins (strobiles) and causes long, tongue shaped galls known as languets to grow from them. These galls seem to like high humidity so are usually found on alders that grow near swamps, ponds and streams. 

Once they’ve reached their limit of growth the tongue galls dry and blacken, and look like this. I think this is something most of us have seen.

Azalea Exobasidium gall is another leaf and flower gall that is caused by a fungus instead of an insect. It can cause swollen shoots, stem galls, witches’ brooms and red leaf spots, but more often than not it causes white galls like that seen in the above photo. The white color comes from the spores of the fungus, which are spread by wind and rain. I found this and many other examples growing on some wild roseshell azaleas.

While I’ve been working on this post we’ve had two days of rain, so I hoped to see some mushrooms. I didn’t have to look too hard; this yellow fly agaric (Amanita muscaria v. formosa) grew in the middle of a trail. I used to do 2 or 3 mushroom posts each year but last year I didn’t find enough to do any, so I was happy to see this one. The name fly agaric comes from the practice of putting pieces of the mushroom in a dish of milk. The story says that when flies drank the milk they died, but it’s something I’ve never tried. Fly agaric is said to have the ability to “turn off” fear in humans and is considered toxic. Some Vikings, called “berserkers”  are said to have used it for that very reason.

I also saw a white slime mold on an oak leaf. Some slime molds can be very small and others quite large. This one in its plasmodium stage was average, I’d say; about as big as the leaf itself. When slime molds are in this state they are usually moving, but very slowly. Slime molds are very sensitive to drying out so they usually move at night, but they can be found on cloudy, humid days as well. I haven’t been able to identify it so for now all I can say is that it is a white slime mold, possibly a Physarum, in the plasmodium stage. Slime molds, even though sometimes covering a large area, are actually made up of hundreds or thousands of single entities. These entities move through the forest looking for food or a suitable place to fruit and eventually come together in a mass. They move with the single mindedness of a school of fish or a flock of birds. So far science can tell us what they aren’t, but not what they are.

And there were Indian pipes (Monotropa uniflora,) which are not fungi but often appear at the same time. Each plant has a single flower and each flower nods toward the ground until it is pollinated. Once pollinated they turn and point straight at the sky, and in that position they will turn brown and become hard like wood, and finally the seed pods will split open and release the tiny seeds. They are dust like and are borne on the wind.

Blueberries seem to be having a great year. The bushes I’ve looked at have been loaded with berries, so the bears and birds will eat well.

Invasive Tatarian honeysuckle (Lonicera tatarica) berries ripen from green to orange to red and for the first time I caught all the stages in one photo. This shrub is native to Siberia and is very tough. Birds love its berries and that’s why it has been so successful. In this area there are very few places where it doesn’t grow. Tatarian honeysuckle was introduced as an ornamental shrub in the 1750s. It has deep pink, very fragrant flowers in spring. Though it is invasive it has been here so long that it’s hard to imagine life without it.

Black elderberry fruit has just started to form. In this stage the big flower heads always remind me of star charts.

Fern balls are created by an insect called either a fern leaf tier or a leaf roller, depending on who you listen to. They appear at the tip of a fern frond and look like a ball. Inside the ball are caterpillars of a moth, possibly in the herpetogramma family. The caterpillars pull the tip of the fern into a ball shape and tie it up with silk. Once inside the shelter they feed on the leaflets.

These are busy moths; I’m seeing a lot of these balled up leaves this year.

The fern that had the fern balls on it was either an interrupted fern (Osmunda claytoniana,) shown above, or a cinnamon fern (Osmundastrum cinnamomeum,) shown in the next photo. Since it had no spore cases on it, it was hard to tell. Interrupted fern gets its common name from the way the fertile fronds look as if they’ve been “interrupted” by spore cases, which are the dark areas on this fern.

Cinnamon fern spore bearing fronds are reddish and whoever named the fern thought they looked like cinnamon sticks. If you saw both ferns growing side by side and neither was producing spores most of us would think they were identical.

Timothy grass has just started to flower. Each flower head is filled with tiny florets, each with three purple stamens and 2 wispy white stigmas. Timothy grass makes an excellent hay crop and gets its common name from Timothy Hanson, a farmer who began to cultivate and promote it in 1720, a few years after its introduction into colonial America in 1711. It should be cut for hay before it reaches this stage but it’s quite beautiful when it blossoms. When you see someone chewing a stalk of grass in a photo or painting it is usually Timothy. I chewed many myself as a boy, and I just thought of the opening line of Ventura Highway by the band America: Chewing on a piece of grass, walking down the road

The oddest thing I’ve seen lately is this piece of cantaloupe i found on a lawn. I once worked with someone who made pens as a hobby, and he told me that he knew some people who used the netting from cantaloupes to decorate the pens they made. I can’t imagine how it was done but I’d bet they were beautiful pens.

This view says summer to me. I grew up lazing on the banks of a river, seeing views just like this one every day. May every child be so lucky.
