Here in Oklahoma, we have the good ole fashion "june bug". It's a brown, (some light/some dark) flying beetle around 1/2 to 5/8 inch long that flys around in the late evening and into the night and have very "sticky" legs. They are harmless, and a great source of protien to the chickens. So much of a great source, I purposely leave flood lights on close to my chicken run, so it attracts them for the chickens to eat up the next day.
They are also your standard "grub worms" that are found in the dirt. They turn in to "june bugs".
I've seen blacker colored ones, and just this year, I've noticed perfectly round holes in my yard, and in them, are GIANT, "june bug looking" things that I guess are.....GIANT JUNE BUGS? My dog decided to start digging out where one of the holes was at, and out it came. So I had the dog dig another hole, and sure enough, another one. They immediately were picked up and thrown in to the run for the chickens to eat.
