What's That?

The other night, our neighbor and good friend, Ron, was walking up his driveway and saw something glowing in the rocks beside his house.

So he went inside and got his camera. When he used the flash on his camera, this it what the picture looks like.

Again in the dark, these worm like creatures appear as a glowing green light.

Ron thought they were some sort of "glow worm"....but someone in the know said they are a type of beetle. All of us have seen fireflies, or as some folks call them,,,lightening bugs. But, these worm like creatures are new to us around here?
