I have no idea where I got this photo, it may have come with my
computer. It is not mine. It IS the butterfly most commonly
called the 'Peacock' or 'Pfauenauge' (though there are others). The
zoological name is Aglais io (alternatively often put in the genera
Inachis or Nymphalis).
Sorry, my computer is acting up tonight, so this photo is not attached in
the usual way. Hope it comes through.
I've been trying to imagine an Iris with a similar color pattern, and the
thing that comes to mind is "STRIKING". It would certainly be a standout,
and would have color combinations that would be to die for.
This is a common Eurasian species of butterfly, but only occurs in the US
as a rare escape, or in collections / captivity.
Our closest relative is the Milbert's Tortoiseshell - Aglais milbertii.
The other Tortoiseshells, the Mourning Cloak, and the Angle-wings (ie. the
Comma, Zephyr, Fawn, and Question Mark) are also closely related.
None are as striking as the Peacock.
