No Butters only Dragons

This is a female eastern amberwing. Size 0.9 inches. Seen here perched on the head of a black-eyed Susan.

This damselfly was on the road, and I am calling it a "purple bluet", though I do not know what it is. My only reference is a web site for Georgia damselflies. I do wish there was a book or web site for dragonflies and damselflies of Pennsylvania or the mid-Atlantic region. Can anyone help?

Halloween Pennant. Size is 1.5 inches. Not the greatest photo, and I have seen this one before.

This beautiful creature is a band-winged Meadowhawk. Size is 1.3 inches. It was feeding on the side of the meadow, but when I returned to this spot later, it was gone. I was lucky to see it.

I am still waiting impatiently for some beautiful butterflies to appear, but I am happy to be learning all these new dragonflies in the meantime.
