Giant Mayfly and not-so Giant Friend

I was about to head into work, saw this beauty, had to get a few pictures before leaving. While squinting through my super dark viewfinder (have to love macro) I thought I could see somethign crawling on it's face. Needless to say I did see something, what a fantastic suprise. When you have that thought of, 'should i go get my camera,I'm going to be late?" the answer is YES!
