Sorry about the poor quality of the pictures. I couldn't get the iPhone to focus
Argiope trifasciata (also known as the banded garden spider in the United States) is a species of spider found around the world. It can be found in certain areas of Europe, namely the Iberian Peninsula, the Canary Islands or Madeira. The similar looking Argiope bruennichi is common in the Azores. Considered a pest in some areas, they typically begin to appear during autumn from early September to late October as temperatures start dropping.
