Portia Spiders are from the family Salticidae which contains the jumping spiders. Portia is a genus of jumping spider which feeds on other spiders (araneophagic). They are remarkable for their hunting behaviour it seems they are capable of learning and problem solving. Portias often hunt in ways that seem intelligent. Their favorite prey seems to be web-building spiders between 10% and 200% of the spiders size. These are also known as the Dandy Jumping Spider. This little one was found in my garden in Port Elizabeth.
