The Euplexoptera are widely distributed over the surface of the earth. The tropical regions, however, can hardly claim any great predominance over more temperate climates as regards either the number or size of the species.

The largest European species (Forficesita gigantea), which is an inhabitant of some parts of England, measures about an inch in length of the body.

Our common Earwig (Forficula auricularia) is not only found all over Europe, but apparently throughout the greater part of the eastern hemisphere.

Another British species, viz., the little Earwig (Labia minor), is also of wide distribution.

The earwig derives its name from its occasionally creeping into the human ear in search of concealment. This has been denied by many authors, but we have personally known instances of earwigs entering the ears of persons lying asleep in fields in the summer time. The insect can be driven out immediately by pouring a little oil into the ear.

Some writers have attempted to prove that the name earwig is a corruption of "earwing," in allusion to the shape of the hind wings; really a very ingenious idea, but incorrect nevertheless.
