Leaf Cutter Bees

Today I had a job Photographing a local business's products for their Website. They make all sorts of interesting things and I was so impressed! 
While I was there, there was another Man who makes these houses to raise Leaf Cutter Bees. I had never heard of them before and it was just so interesting! He gave me one in exchange for photos for his Website too. The little green things at the bottom are the cocoons which grow into bees.  They don't produce honey they just pollinate plants. I'm so looking forward to watching them grow.
