Answer:
I am small and green and hop around. I start my life with a tail but lose it as I grow. What am I?
It can be in a hat, Or out of the bag. If you see it you'll be smitten, 'Cause it's fluffy like a mitten.
It's small but larger than a bee, And agile as a flea. It humms but does not buzz, And it's not covered with fuzz. It is a small collector, Of juicy flower nectar.
It is an insect, and the first part of its name is the name of another insect. What is it?
A nutcracker up in a tree
You use it between your head and your toes, the more it works the thinner it grows.
