This is timely! I was just about to search this forum for information about milkweed and to see what I could do to help out the Monarchs. The top one looks like a Monarch to me. Sad.
I found a dead honeybee on the top of my rain barrel the other day. Before, I wouldn't have given it much thought but I was really saddened by it, with bee populations on such a serious decline.
Don't know what the second one is... pretty flower it is sitting on tho!

That is a monarch - they are poisonous to birds and apparently taste really bad - so that's probably why the robin spat it out.

The little moth I think is some sort of Tiger Moth - I will try to figure it out.

Susan, can I post your moth picture on an insect website to get an ID? I almost did it but decided I'd better get your permission first.

Yes, please go ahead and post. I knew there was a site for that but I couldn't remember what it was. Thanks!

Aha! White Spotted Sable Moth, Anania funebris. I love that site. Bugs are awesome!

Here is a link that might be useful: Bug Guide ID

Thanks Gil! The service at this place is very speedy :-)
I'll have to make sure to add that site to my favorites.

That little guy is very cute and I'm keeping my fingers crossed for more Monarchs.
