The Viceroy. #1 which is none poisonous, while the monarch is poisonous because it's caterpillar eats milkweed which is poisonous. Birds leave the Viceroy alone because they think they are the same.

Interesting, but my gut choice was correct. Thanks for pointing that out.

Very nice set! 👍
And they ‘all look the same’ to me. How can I easily tell what my library holds?

Thanks to all who responded; I appreciate your comments!
About the easiest way to distinguish the Viceroy from the Monarch is that the Viceroy has a prominent black stripe parallel to the edge of the wing on its hindwings.
It has been traditionally thought that the "nontoxic" Viceroy benefits from mimicking the toxic Monarch. True, the Monarch is toxic because they eat milkweed in their caterpillar stage, and milkweed contains cardiac toxins. Well, it turns out that Viceroy caterpillars eat willow, which contains salicylates (aspirin, or acetylsalicylic acid, originally came from the bark of the willow tree) making them distasteful and somewhat toxic, though not potentially lethal like the Monarch.
