Painted Lady Butterfly (Vanessa cardui): We’re reposting this photo from a few weeks ago. Starting in mid May, Painted Lady butterflies started showing up in western MT. Migrating from northwestern Mexico, the number that migrate vary tremendously from year to year. This year is a BIG year. On a recent outing, we saw dozens of painted ladies zipping by (they are extremely fast flyers). Photo by Glenn Marangelo on 5/20/17 at the National Bison Range, MT.
