The Spider ran round the whole bird bath over and over and was cautious about the water But he used a stick which he took a liking to and used it as a bridge to touch the water with hisLeg and mouth and go all the way back to the top again. He realises the water is ok and course Ready to catch some flying ants. When the spider was gone One flying Ant had fell in the bird bath but I put her on the wall with the other active flying ants in the sun to dry off and carry on.I think the birds and exspeacialy the gulls enjoyed the flying ants aswell. with nuptial flights some Do manage to go off and mate successfully without getting caught by predators.
