Couldn't believe my luck in catching two monarchs at once - there were actually 3 on the bush at the same time. I know the front one is a male because of the 2 back "dots" on those bars (thanks to Hope Jennings) but don't know about the other.
@falcon11 thanks for the "how to" - I tried that and it did definitely make the top one show better without sacrificing the contrast. You're a great source of learning for me.
