Queens.
Smaller cousins of Monarchs.
Monarchs pass through during migration. Queens are more stationary tropicals. We’re at the north end of their range, so we get to see them year-round.
This one is different.
It’s a White Peacock.
Like the Queen, it’s a tropical butterfly and non-migratory. The Queens will all gather together to feed. The White Peacock is more territorial, and is more likely to be seen solo.
