Surprising Colors

      Today started out cloudy, cold and windy. The word “dull” came to mind.

                                                                                                                      We’d had an ice storm during the night.

                                    I  went out after breakfast to walk around the  yard. All the ice reflected the gray sky. I took a few pictures to remind me of the ice storm. I just realized I’d overlooked one picture that I’d taken:  It has such an artistic design with a combination of the colors in the background and the linear shapes in the foreground.

The colors set the mood for the day … unless the weather changes.

This picture shows linear movement of the ice-colored twigs on a near-by tree.

This picture was taken about the same time as the one above. Both were taken in our backyard.

It shows the results of camera movement and the early morning light.

A Pruner, a Girdler and a ?

We have a dawn redwood tree in our backyard

that my mother gave us years ago. These pictures were taken the end of November.

I found several twigs on the ground under the tree.

What “cut” the twigs from the tree, and how did they do it to make the end look like that?

There are tree pruner insects. A full-grown twig pruner chews through the wood from the inside out. This leaves a smooth cut on the inside of the twig. The ragged edge results from the twig breaking.

This broken twig resulted from a female tree girdler chewing a v-shaped groove around the twig. The small larva overwintered in the fallen twig.

The ones off the redwood tree don’t look like the work of a girdler or a pruner.

It will probably remain a mystery … unless I find another clue in the future.
