Mutant fly?

I wanted to share this odd looking fly with you. I never seen one like that before. I’d love to shoot such photo on different background because this one doesn’t work good, but as you know you can’t choose where fly will land :) I also missed focus by a tiny bit and DOF is too shallow, but it was either this shot or no shot at all.
