It does look like a butterfly! Ooooh, sparkly!
Made me think of this quote (don’t know why):
“Little girls, like butterflies, need no excuse.” - Robert A. Heinlein, “The Notebooks of Lazarus Long.”
If you live up in the northern tier of states, don’t go trying to see this unless you got a flat horizon. Down South, it’s low enough, up there, it hugs the ground.
It’s a great site on a dark night.
Looks like firefly to me.
