Very pretty
If anyone reading this can comment on the iridiscence in this hoppers wings, I would appreciate it. There was a recent post of a black fly with strong iridiscence in it's wings, and I've seen it occasionally on certain tree crickets as well, and would like to understand what causes it.

 
Info on iridescence...
I found this article on the website for the University of Exeter and it was originally published in the "Physics Review", Sept 1998, by Philip Allan Publishers. Although the article is focused on the occurrence of iridescence in lepidoptera, I would think that the wonderful amount of detailed information provided could be extrapolated for other forms of insect iridescence. Hope this satisfies some of your curiosity!

Thanks, Harsi -- it was fascinating
...I had to read it a couple times (well, actually the most important paragraph was read several times)...but I finally got it :) Thanks for the tip.
