Silver Argiope Spider

thanks gentleman. there are only four possibilities for this one. the argentata is the most reasonable. the coloration, in brilliance and shape, on this particular speciman was unlike any I saw on the web.

Yes indeed you may be right... I think the savignyi is known to make a silk "disc", but I am no expert. Upon your suggestion I did a bit if research and found the S. savignyi has been observed preying upon bats!!! Now that is freaky! http://caribjsci.org/dec07/43_273d-284d....

@ulvalactuca77
Check the pattern also of that White silk signature... may X type in many species of Argiope spiders...

oh, haha. Late to the party as usual.

That's^ a Silver Argiope (Argiope argentata) http://naturecloseups.com/?s=argiope The X in the web is typical of them..

Deleted my ID suggestion... Thought of savgnyi specie...
ulvalactuca77 is correct..

This is exact ...

You are welcome. Can't go further... hehehe

Entonces esta coloracion que tiene es variable dentro la especie o es una especie indeterminable por las fotos ke tengo?

The A argentata es la mas comun, en Costa Rica.

Any ideas Jonathan?

I have narrowed this down to a Silver Argiope Spider but I am not sure of the species.

Tommaso, thanks for the lead!

I guess is an S. Andrews cross spider because the position of the legs and the white thick line in the web. Don't know witch species though.
