Tinkerbell shows up again. large pulsing sphere in background

I normally wouldn't pay much attention to small objects but seeing as how Im not emitting any light source like Infrared and knowing that we have thousands of bugs flying around I've noticed this small basket Ball sized orb twice now. it's self illuminated in the invisible light spectrum as my scope picks it up. when it powered away the last time after it flashed me , it was fully illuminated away from me as it shot off past the tree top
