This fly landed on my left hand while I was taking some 'free hand' macros (no tripod). I decided to try and take some one-handed photos of it and these are the results. Unfortunately, I didn't realize that it was going to suck my blood when I started the process. This photo was actually the last one taken in this sequence. I'm not sure but it looked to me as I looked through the viewfinder that the fly's body was getting redder as it drank more of my blood. Is it possible that the reddish cast is my blood showing through the fly's body rather than just a reflection off my hand? Also, I'm curious about the bubble that appeared at the posterior end of the fly as it was finishing its 'meal'. I hope it didn't both eat my blood and then 'relieve' itself on me too! Image number 040611 is a similar angle view of the fly before the bubble developed. BTW, do all flies drink blood if given the chance? Hoping for an ID of course.
