Cetonia aurata, C.G.Jung and synchronicity

Today I came along the same bush I wrote about in my previous post ”Visitors”, describing a merry buzzing group of diverse insects. A surprise! This time the  entire bush was conquered by rose chafers solely,  each of them resembling a small green armored vehicle cruising  over white flowers.  Due to special circumstances C.G. Jung would call this synchronicity, a meaningful coincidence a subject finds between causally unrelated events. It made me think, anyway……………..

 

In his book Synchronicity (1952), Jung tells the following story as an example of a synchronistic event:

A young woman I was treating had, at a critical moment, a dream in which she was given a golden scarab. While she was telling me this dream, I sat with my back to the closed window. Suddenly I heard a noise behind me, like a gentle tapping. I turned round and saw a flying insect knocking against the window-pane from the outside. I opened the window and caught the creature in the air as it flew in. It was the nearest analogy to a golden scarab one finds in our latitudes, a scarabaeid beetle, the common rose-chafer (Cetonia aurata), which, contrary to its usual habits had evidently felt the urge to get into a dark room at this particular moment. I must admit that nothing like it ever happened to me before or since.[14] from: http://en.wikipedia.org/wiki/Synchronicity

Masquerade and Plants

There were many beautiful illustrations in the old zoological textbook I wrote about in my last post. Today I’ve picked some illustrious examples of what is known as masquerade or mimesis. Basically, prey animals during evolution developed mechanisms, to camouflage and have higher surveillance rates. Mimetic animals look like something else, not interesting to the predator, like bark, twig, leaf or even lichen. You have the examples on the pictures above, they are actuary  full of  mother nature’s wit. But could it be presumed, that mimesis is a form of  aggressive influential behaviour? Meaning ,that flora in general, is in a way pushing other species to try to survive by being more flora like. Which in turn ends in better surveillance rates of real flora, as the, so to say, fake mimetic subjects de facto are ”incompetent plants”? Would like to hear your opinion about this science-fiction idea!

illustrations from: Erjavec F.:Ptice;  Celovec 1893

I love old books , It amuses me to read archaic Slovene language, old illustrations are magical.  I’ve picked these illustrations from an old Slovene book about nature, where , among others, author stands fascinated about the artistry of little birds from Africa, able to make spectacular ”condominium” nests . There can live up to 3 hundred families in neighbour nest cells. First picture above shows the early phases of such a nest and the second picture shows it finished ( woven with grasses and tiny sticks). It is the biggest structure birds can build. A sort of bird’s megapolis.

It is interesting that these birds are not endangered today, for they are able to find so many artificial building materials around human settlements, that they have excellent conditions for their nests and therefore for many new families. And these are two good stories that made me write today’s post: I am happy to find an old Slovene book about nature in excellent condition, with great illustrations , and I am happy to learn that not only book, but also these birds made it into modern times……

 

Erinaceus concolor or somebody wandering alone in the night

As I met this little guy wandering trough the garden I had to publish his photo. Not only for he is so cute, even not for he does such a good job in the garden but for I was surprised to read all the scientific articles dealing with this little creature.Among the more interesting ones is the one about glacial eras and hedgehogs migration.Or the one about hedgehogs menu in urban area.Or about the shape of its cranium. I really wonder what influences the choice of scientific interest upon a certain subject-for.example why nobody investigated for.example hedgehogs in the art ? Is it.possible.that our archetypal picture of certain subject prejudices the interest we would develop about it? For this could mean that the investigations in science could be under different archetypes oriented towards different topics???
Anyway, this may be too much for a young hedgehog wandering trough my botanical garden…….

Antheraea yamamai -from silk to Mach number

PICT0300

It is a hot August whether these days here around, the temperatures above 30 degrees C for almost two weeks.Only nights are a bit cooler,we stay awake quiet late. Yesterday evening was the same,we were watching TV as a strange visitor came in-a yellow, huge moth was flying across the room almost like a bird,then he sat down on a plant and remained there long enough for us to make some pics. We’ve seen such a big moth here for the first time-and have been very impressed by his story.

Yamamai or Japanese Oak Silkmoth has been cultivated in Japan for more than 1000 years,its silk is white,elastic,durable and very expensive.Adult moth has a wingspan of 10-15cm.Its larvae feed on quercus while the adult moth doesn’t eat at all,he has enough energy to fly for a couple of days and to reproduce,then he dies.In the middle of 19-th century family Mach has settled in Veliki Slatnik (Slovenia).In 1866 Johann Mach imported yamamai eggs to start with the production of Shantung silk .The business didn’t succeed ,but the yamamai butterflies succeeded to survive in new habitat ,even more, from Veliki Slatnik they spread to whole Balkan, Italy,Austria,they have been spotted in Germany. Johann Mach and his wife are buried for a long time.Their grave at the cemetery of Veliki Slatnik is almost forgotten. Yet whenever yellow yamamai   appears here around, he brings with him a story of family  coming from far to live in these rural area,with a strange idea of producing silk and leaving this beautiful moth to fly further to Europe.And there is still another story yamamai brings with him, a story of Mach son ,loving the land around fathers farm that much that he was returning back home for his holidays.Professor of physic at the universities of Graz,Prague,Vienna wrote some of hist best works at the farm where his father explored the conditions to suit  yamamai silk production best.And who this son was? Ernst Mach, great physic and philosopher of time,Mach number is just one of his many contributions.So  from now on when I will see a yamamai I will remember Veliki Slatnik, silk and Mach number……..

Ernst Mach (German pronunciation: [ˈɛɐnst ˈmax]) (February 18, 1838 – February 19, 1916) was an Austrian physicist and philosopher, noted for his contributions to physics such as the Mach number and the study of shock waves. As a philosopher of science, he was a major influence on logical positivism and through his criticism of Newton, a forerunner of Einstein‘s relativity.from:http://en.wikipedia.org/wiki/Ernst_Mach

In fluid mechanicsMach number (\mathrm{Ma} or M) (generally play /ˈmɑːk/, sometimes /ˈmɑːx/ or /ˈmæk/) is a dimensionless quantity representing the speed of an object moving through air or other fluid divided by the local speed of sound.[1][2] It is commonly used to represent the speed of an object when it is traveling close to or above the speed of sound.from:http://en.wikipedia.org/wiki/Mach_number

No matter how I’ve tried,I’ve newer recorded such a success with my garden efforts as did I with simple act of planting Wisteria sinensis alba about ten years ago.I am absolutely noncompetitive gardener,but must admit that it feels good when my neighbors stop by our house in simple admiration of white waterfall,I’ve noticed even some envy in eyes of my dear next-door neighbor having blue variety of wisteria which doesn’t want to flower.But there is something I enjoy even more as flattery during May, when my wisteria is  just as magical smelling cloud-it is sitting on our wisteria terrace and observing many bees and bumblebees constantly flying among scented flowers.There are so many a buzz is becoming  a sort of music,vanishing with wind and appearing stronger again and again.The same one bumblebees are coming back to eat sweet nectar again and again,day after day!Well, this is called flower constancy (and not,as one might assume the constant beauty of my wisteria) although from my point of view it could be called bumblebee constancy!

Bumblebees will also tend to visit the same patches of flowers every day, as long as they continue to find nectar and pollen,[11] a habit known as pollinator or flower constancy. While foraging, bumblebees can reach ground speeds of up to 15 metres per second (54 km/h).[12] from;http://en.wikipedia.org/wiki/Bumblebee

Grasshopper movie star

My petunias eaten? Green grasshopper was near by ,so I claimed him guilty.To feel better about it ,I went on net to check it out.I am calm now, grasshoppers do eat plants,indeed.But I’ve got another question by now-I’ve remembered old Aesop tale ”Grasshopper and ant” and I wonder does this assumption about lazy grasshopper have any realistic backgrounds or was it just made up for didactic purposes by Aesop? For my grasshopper was quiet laborious to cut so many petunias as it did……Nevertheless,I have found two old grasshopper films on you -tube.Both of them around 100 years old, yet ending a bit different one from the other-to fit didactic needs of the time.Which could mean, that also Aesop made it up,too.Of course My Botanical Gardens in this case absolutely disprove use of grasshoppers good name in a way that has no realistic grounds ;). But please, do have a look-and enjoy! Any scientific explanation about grasshoppers working habits is welcome!

Grasshoppers prefer to eat grasses, leaves and cereal crops. The majority of grasshoppers are polyphagous. Many will eat from multiple host plants in one day, while some prefer to rely on the same host plant. Only one of the 8000 species of grasshopper is monophagous and will only eat a single species of plant.[2]
