A Mid-winter's Sidebar

I'm getting cabin fever, I'm sick of the drama in the Middle East, and the bluebonnets are starting to bloom in Texas which is making me nostalgic. So I was flipping through a back issue of "Texas Parks and Wildlife" magazine, leftover from the days when I worked there (for TPWD - not the magazine) and I found an article on these lovely little creatures with names like characters in a Shakespearean comedy or a J.R.R. Tolkien fantasy. Care to guess what they are?
