You know you need a one-stop shop for all your high-res, ginormous bug photo needs. Here it is, a great collection on Flickr for your Entymological pleasure.
If you click on any of the pictures, above the display is a little text link called "all sizes." It is there that you can get the big, juicy pictures you need to create wallpaper and screen savers with.
No no, you don't have to thank me, really.
Some pictures from the collection to whet your whistle:
Enjoy getting up close and personal with some bugs,
