I've been a little disappointed that I haven't seen more Painted Lady (or their American Lady cousins) this season, but I did find a pair early in the summer at Sourland. (I believe these are pictures of separate butterflies, though all I can say for sure is that there were 2 there, and they'd occasionally flutter in the same general airspace, making it hard to track the individuals.) This is considered the most widespread butterfly in the world, with populations living in the Americas and in Eurasia/Africa. They also engage in absurdly long migrations, especially some that range from Africa to northern Asia. You can tell the first picture is a Painted Lady because the orange in the forewing lacks a small white dot. That dot is a key differentiator from the American Lady.

Here's an American Lady butterfly I met a couple months ago. This picture might not be National Geographic quality, but there's one thing I like about it. It demonstrates the 2 ways to differentiate the American Lady butterfly from its Painted Lady butterfly cousin. If you have a view of the top of the wings, look for a small white dot completely surrounded by an orange region of the wing. American Ladies have that spot while Painted Ladies do not. And if you have a view of the bottom of the wings, you can see "eyespots" on the back wing. American Ladies like this one have 2 eyespots, while Painted Ladies have 4. Other than this, these 2 butterflies are pretty similar. Both are in the same genus, and both migrate to avoid northern winters. I think the Painted Ladies are more common overall; certainly I've seen more Painteds than Americans. May 14, 2021 at Fairview Farm Photo 132039233, (c) jpviolette, some rights reserved (CC BY-NC)
