Answer:
The more you look at me The less you see.
When I am caught I am thrown away. When I escape you itch all day.
First you see me in the grass dressed in yellow gay; next I am in dainty white, then I fly away. What am I?
I am what one cannot keep, two cannot hold, and three cannot destroy. What am I?
Always in you, sometimes on you. If I surround you, I can kill you. What am I?
A little house full of meat, no door to go in and eat.
