Why does a glow worm glow?

WHy does a glow worm glow?

Holla!

Its your boy here again with something to view, this one's about the glow of a glow worm. Keep reading and activate the science you.

A glow worm is not a worm at all but a female beetle.  Nor is a firefly. It, too, is a beetle, and it also glows, or flickers.

A wingless female glow worm must attract males to fertilize the eggs she lays. She makes the rear end of her body in the dark. The male can see the light and recognize it as coming from a female glowworm. The eggs of this beetle glow a little.

Fireflies glow to attract mates, too, but in fireflies the males also glow.

There are several interesting facts about the glow. It is a "cold" light - unlike the familiar "hot" light from an electric light bulb. Yet it is different from manufactured cold light such phosphorescent paint used on the figures and faces of watches and clocks so that we can tell light in the dark.

Scientists can not completely explain the light of a glowworms glow or how fireflies sometimes flicker all al the same time. It is usually easier to see a faint light a long way off if it goes on and off, than if it stays on all the time. Glowworms glow and fireflies flicker to make it easier to communicate to their mates.

So we know some of the whys about the glow of these beetles.

Stay tuned for more.
