Regarding sexes, To be honest, theres only one I see that I would definitively call a male. The rest are questionable. IMO, and IME, both males and females do exhibit some faciual patterning, whereas the males have a vivid, entrancing "netting". The picture is too broad to see such detail, and as such, I certainly wouldnt call them all males, in my opinion.
