Monarch Butterflies

I love monarch butterflies! Butterflies in general are so whimsical and make me feel 12 again. I was lurking through my media files and happened upon this folder labeled ‘fall walk’. Well, that was a pretty uneventful title for a nice set of pretty flutter-bys!! I’m not even sure where these were taken, but who cares 😉 Just enjoy them.

imageThey like the late season bonanza found on Joe Pye Weed and the Queen Anne’s Lace make nice landing pads.

The origin of names has always fascinated me. So, who was Joe Pye and why does he have a weed named after him?? I found quite a large amount of research on the topic. For a Cliff’s Notes version, read below:

Joseph Pye of Stockbridge could have had an ancestor from Salem who treated colonists for typhus thereby making his “fame and fortune,” or his name might have been a corruption from a hypothetical Indian word for typhus or some similar disease.  But I ask: Why not embrace the hard evidence that Joseph Pye was a Mohegan sachem who lived in western Massachusetts precisely where Eaton tells us that “Joe Pye’s Weed” was in “common use” as a treatment for typhus; that he lived his notable life there just a few decades before Eaton remarks on Joe Pye’s Weed; that the president of the college where Eaton lectured believed that he successfully treated his fever with a tea made from Joe Pye’s Weed; that Joseph Pye was educated by Samson Occam, himself an herbalist?  All this is substantiated and frankly I believe makes a better story than any borne of speculation.

Of course, monarchs love milkweed. If everyone could just plant a few of these in their yard, we would truly be able to help their populations.

Giant Leopard Moth ~ Hypercompe scribonia

image
This little guy is in his ‘Don’t eat me!’ a posture that protects his underside and flashes the orange stripes, which usually mean this meal is unpalatable.

The Giant Leopard Moth or Eyed Tiger Moth (Hypercompe scribonia) various forests having host plants on which the caterpillars forage extensively. Gardens, farmlands, woodlands and public areas can be frequented by them.

Females emit pheromones that are caught by the antenna of the males that successfully locates the female for mating. When mating is over, the female gets on with the process of laying eggs.

Adults fly from April to September

After the eggs are laid, the larvae come out of them which start feeding on the leaves where they emerge out of the eggs. As caterpillars, they assume the wooly bear appearance and go into hibernation for some time during the winters. But it might as well wake up for light foraging on milder days in the temperate regions. After sleeping over winter, it weaves cocoon from its body. It becomes the pupa after molting in the wake of spring. In the next few weeks, it transforms into an adult moth.

Host plants for larvae: cherries, plantains, violets, honeysuckles, magnolia, cabbage, sunflower, lilac, dandelion, pokeweed, willow, maples and other broad-leaved plants.

The dorsal aspect of the abdomen is iridescent, blue-black with orange lateral spots or occasionally orange with large blue-black spots. The legs also have iridescent, blue-black setae.

When threatened, adults ‘play possum’ and curl their abdomen to display their bright orange stripes. They also secrete a droplet of yellow, acrid fluid from the thoracic glands that is bitter tasting.

Sunrise Sunset – Why Are They So Colorful?!!?

Early Sunrise

Sunrise

The sun produces a wide range of frequencies, with a number of these frequencies falling within the visible light spectrum that humans are able to see. Since sunlight consists of light with a wide range of visible light frequencies, it appears white. The interaction of visible light and matter will result in the absorption of specific frequencies of light. The frequencies of visible light that are not absorbed are either transmitted (by transparent materials) or reflected (by opaque materials). To explain this theory, consider a green leaf on a tree, the atoms of the chlorophyll molecules in the leaf are absorbing most of the frequencies of visible light (except for green) and reflecting the green light to our eyes. The leaf therefore appears green. Another example would be to view the black asphalt street, the atoms of the asphalt are absorbing all the frequencies of visible light and no light is reflected back to our eyes. The asphalt street thus appears black (the absence of color). In this manner, the interaction of sunlight with matter contributes to the color appearance of our surrounding world.
The appearance of the sun changes with the time of day. While it may be yellow during midday, it gradually changes color as it approaches sunset. This is called ‘Light Scattering’. As the sun approaches the horizon line, sunlight must traverse a greater distance through our atmosphere.

sun rays

As the path that sunlight takes through our atmosphere increases in length, visible light (ROYGBIV) shines through more atmospheric particles. This results in the scattering of greater and greater amounts of yellow light. During sunset hours, the light passing through our atmosphere to our eyes tends to be most concentrated with red and orange frequencies of light. For this reason, the sunsets have a reddish-orange hue. The effect of a red sunset becomes prominent if the atmosphere contains more particles. The presence of sulfur aerosols that are produced as an industrial pollutant and by volcanic activity in our atmosphere contributes to some magnificent sunsets. Although it also means we have some very serious environmental problems.

Sunset, that same day.

A fav song of mine:

Sunrise, sunset, sunrise, sunset
Swiftly go the days
Sunrise, sunset, you wake up then you undress
It always is the same
The sunrise and a sun sets
You are lying while you confess
Keep trying to explain
The sunrise and the sun sets
You realize and then you forget
What you have been trying to retain

But everybody knows it’s all about the things
That get stuck inside of your head
Like the songs your roommate sings
Or a vision of her body as she stretches out on your bed
you raise her hands in the air
Ask her ‘When was the last time you looked in the mirror?
Cause you’ve changed, yeah, you’ve changed

The sunrise, the sunset, you’re hopeful and then you regret
The circle never breaks
With a sunrise and sunset, there’s a change of heart or address
Is there nothing that remains?
For a sunrise or a sunset, you’re manic or you’re depressed
Will you ever feel ok?
For a sunrise or a sunset, your lover is an actress
Did you really think she’d stay?
For a sunrise or a sunset, you’re either coming or you just left
But you’re always on the way
Towards a sunrise or a sunset, a scribble or a sonnet
They are really just the same
To the sunrise or the sunset, the master and his servant
Have exactly the same fate
It’s a sunrise and a sunset, from a cradle to a casket
There is no way to escape
The sunrise or the sunset, hold your sadness like a puppet
Keep putting on the play

But everything you do is leading to the point
Where you just won’t know what to do
And the moment that you’re laughing
There is someone there who will be laughing louder than you
So it’s true, the trick is complete
You’ve become everything you said you never would be
You’re a fool, you’re a fool

Sunrise, sunset, sunrise, sunset
The sunrise and the sun sets
Sunrise, sunset, the sunrise, the sun sets
The sunrise, the sun sets

Sunrise, sunset, go home to your apartment
Put the cassette in the tape deck
And let that fever play.
