2 comments on “Invasion of the Giant Swallowtails

  1. We saw one in our backyard in Pike Creek, DE on Sept 1. First time we’d ever seen one!

  2. Both my husband and I have spotted a Giant Swallowtail in our garden in Edgemont Township, PA at different times this summer. We both had the same response: “I think that’s a Giant, but I’m not sure since I’ve never seen one before.” We both decided we were right after seeing the yellow under-wings and crossed yellow lines on the top of the wings. The size of the butterfly was the final deciding factor in our identification. We also feel that this has been a banner year for Tigers and have seen more dark form females than ever before.
