Regarding the Giant Swallowtails and knowing the difference between the males and the females, i've discovered that on the upper wing (dorsal view) the female GST has a black spot in the 3rd yellow oval. The third yellow oval on the male GSTs is solid yellow. Here is a dorsal view of the Wednesday GST showing that it is a female. Unfortunately, i did not get dorsal views of the Thursday and Friday GSTs, but in this group, there will be a Saturday or Sunday GST as well.
