Fascinating! I have a dozen dead butterflies, pinned in frames at home (I really like http://www.bugunderglass.com/ if anyone's interested in unique home decorating -- I'm not associated with them in any way, but I've been buying their bugs for almost 6 years now!) and I used to raise moths from local caterpillars when I was a kid (you know, back before I found computers and actually played outside).

I knew the difference between dead and alive butterfly/moth wing positions, but never consciously noticed the difference in artistic depictions. Heck, I volunteer at the Boston Museum of Science every week and must have seen that Monarchs poster a hundred times without noticing.

Comparing art that "did it right" and art that "did it wrong" -- yeah, if you do it right, it looks a LOT more realistic and "lively," even if I wouldn't have known why before reading this article. I'll have to keep an eye out from now on!
