I then noticed a couple of others and scanned the area trying to come up with the total number of Crimson Patches. Then I saw this blob of several more of them.
More ovipositing was occurring.
And looking a little closer it was clear that in all the excitement they were getting a little sloppy about where they were placing their eggs.
With the weight of the eggs all on one wing her flight was pretty labored. I imagine a bird or a lizard will probably get her.
It was quite a show.
And I topped it off with a calling Willow Flycatcher which is hard to find down here.
