What is This Tiny Green Bug?

I find this bug on my arms. It is a little smaller than a pin head, the color is like the light color green on army fatigues. I can't see the legs or much of anything else for that matter because it's so tiny.

I'll be sitting on my recliner and all of a sudden I feel a tickling. I start looking for the source of the tickle and I find it on my forearm or my hand, nowhere else yet.
