Glowworm
a beetle famous for emitting light. The common glowworm of English literature is the wingless and, therefore, wormlike female of a beetle closely related to our firefly. This insect is about half an inch long, black, with dusky reddish legs and a marginal line of the same color. Like our firefly, the glowworm is nocturnal. The last segments of its body emit a steady, strong, soft, bluish gleam. As the light-giving female has no wings, it is easily caught. A couplet from Hamlet gives a glimpse of the hours Shakespeare kept and of his keen observation:
And 'gins to pale his uneffectual fire.
Evidently the poet did not know that it is the female that glows. "The glowworm," says Mr. Edison, "can do something we have not learned to do. It can give light without heat." For a further discussion see FIREFLY.
