Lightning Bugz Screensaver

Every summer evening, rising from the cool grass, or emerging from the trees, comes a swarm of tiny lights. Swirling about, in glowing motion, they search for their mates. They brightly blink in anticipation, hoping their display will bring them their goal.
These magical insects, found mostly in warm, humid climates, are not "flies", but are actually beetles. The male firefly, or lightning bug, uses his bioluminescence to attract a mate.
