Was it the Giant owl butterfly? That has what looks like "eyes" on the wings. I am trying to figure out what something is that I found as well! I saw what looked like a giant monarch butterfly the other day. The body had to be as thick as a rolln of quarters and slightly longer than that. I have not been able to find anything like it on the web as of yet...

I have moved your question to its own thread so that the answers you get will be to your question rather than the archived one.

What part of the world are you in? This is an international site and the lepidoptra of the various continents are very different.
