Wasp spider

We shot this Argiope Bruennichi yesterday morning.

On the web we can see the zigzag shape called the stabilimentum, or web decoration, featured at the centre of the orb is of uncertain function, though it may be to attract insects.
This one could be a male (the male of the species is much smaller than the female).

We had to use flash because the web was very low and the bg too bright and the subject resulted too dark; we tryed with the reflecting panel but it was not enough.
We don't like to use flash very much, but set at -2 in this case it is not so evident.

Thanks for looking
