Monarch Danaus plexippus

Easily the most famous butterfly in the US and possibly the world. And it is a stunning animal when fresh. Powerful fliers and known for the long migrations to their collection trees in Mexico, it is hard not to appreciate them. I have watched hundreds and hundreds float over on October days headed toward Texas and farther south. Males have two dark scent glands on the hindwing that the females lack. It is not well known but if you catch one and hold it to your nose it often smells of whatever flower that Monarch was concentrating its nectar efforts upon.

Male with the dark scent glands visible.

Big September Monarch that is absolutely fresh. Very few wing miles on this one.
