The bumble bee

I have not witnessed a bumble bee with such an orange bottom end?  I looked on line briefly but could not find my answer...regardless he was simply beautiful...and I was once again caught without the 'right' lens...as I am allergic and this is as close as I could get with an 85mm lens!!

I changed the background colour on the second one to accent the colour!

and the third one I think I will turn into a puzzle???  Thoughts?? or Challenges?? ;-))
