Tiny pale blue, white and beige butterflies?

[will-o-wisp]

I didn't do a very extensive fall or spring clean up and the reward, besides not doing all that extra work, is an abundance of very small butterflies or moths. They move too fast mostly to get a good look, although 1 clearly was pale blue on the undersides and another white one spread out flat on a violet leaf and I could see a lacy pattern on the edges of the lower wings, quite elegant.
A lot of them are pale brown and have been dislodged and fly away because I am watering with a hose.
They are very tiny, much smaller then the cabbage whites. Any ideas about what I'm seeing?
I've been checking online butterfly sites and am not sure if i have some spring azures for the blue undersides?
Anyone in or around NJ seeing similar small butterflies?

My first thought was blue azure--but they seem to have blue only when the wings are open...when closed they seem much more drab.
