Although it doesn't look like one, this is a beetle. To me, it appears very similar, although larger, to the glowworms I found hunting on the sidewalk away from the bright lights (where their light was visible), hence the identification. These glowworms emitted a soft green light. Mature males have wings but mature females look much like the larvae (juveniles) and never develop wings. The larvae are predators. This picture shows either a larva or a mature female.
