These guy’s (?) were taken in north Alabama. Don’t know exactly what they are doing or what they are.
We know some things and can speculate on the rest. These are Green Lynx Spiders, Peucetia viridans, our personal favorite spiders. The spider on the left, or as we reproduced your image, on top, is a female. The other appears to be a male. This seems to be a mating ritual. It could end in dinner for the lady. Great photo.
