ABC Wednesday St Andrew's Cross Spider for X


Posted by Picasa


This very well known spider is also known under the name 'garden spider'. I took this photo in Australia, while we were climbing to some rocks to see rock paintings.This one is called : Argiope ocyaloides.
There are 25 known species in this genus but the most beautiful and spotted one is the Argiope Keyserlingi ( formerly aethera) or 'St Andrew's cross spider'

The spiders of this family are easily identified by the zig zag silk construction (stabilimentum), usually a cross, they make in their web.
It is believed that the spider uses it to camouflage itself in the cross and to warn birds not to fly through the web.
But there are also other hypotheses.
Perhaps the most important function of stabilimenta is to attract insects. The silk of the stabilimentum reflects UV light and pollinating insects are lured to these threads.
If the spider is attacked it starts shaking vigorously in her web. The whole web becomes white because of the stabilimentum. This frightens off attackers.
The web is usually constructed a few decimeters above the ground in tall grass and among shrubs.
The spider on this photo however had made its web on a rock, but you can see the zigzag construction of the web around him. For more information and pictures of these spiders go Here

I had a very cool garden spider that lived in our yard this summer. Wonder if it was one of the 25 varieties.

Interesting post.

These spiders are so fascinating! Are they the same as orb spiders? To see the intricate webs they fashion is amazing. Great post!

Interesting story about this spider, Wil. I have a number of spiders here and different kinds from the Garden Spiders to the deadly Wolf Spider. They provide a valuable service to mankind and to many other animals.

I did photograph one spider one summer. I gave her a human name, "Maude," and would talk to her just like she was an old lady living down the street. She stayed in the door corner and spun her web from there. I almost always had to duck under the web and would tell her to move the bottom up higher so I didn't have to stoop each time I went into the storage shed.

And, to my utter surprise she moved it up and out of my way.

All of the things you read that I left on Michelle's blog are my wishes again.

Xtraordinary shot!
Thank for your kind and interesting comments on my blog_(and eXcuse my numerous mistakes !)
I din't know that Napoleon wars changed the pronounciation of Dutch words .
In fact,sometimes we pronounce X CS), sometimes (Gz), sometimes (Ss) or (Z)
We met many Dutch people during our Holidays , in campsites of Périgord, for example-In France-they are very talented to speak foreign languages, espeially English and French .I think it's because of your way of teaching languages at school .
I wish you an eXcellent new year !

Thanks

Very interesting, but not as appealing as the oliebollen in your previous post (as part of the calorie controlled diet, of course).

Best wishes for 2009!

Miss_Yves said...

Thank you very much !
About "mannequin"it's very funny,because, according to Albert Dauzat, a famous author of a Dictionary, ," mannequin "appeared in 1467, and came from ...néerlandais," mannekijn", diminutif de "man", "homme" !
Many of the other (french)words come from Latin language, of course (statio, station, moda, mode...)
