Earwigs - Dermaptera is their scientific name - are fairly common animals. Despite that or maybe because of that their biology has been rarely examined in detail. Engaged amateurs and professional biologist regularly searching for Dermaptera are rare, much in difference to other groups of organisms such as butterflies, moths, dragon flies and crickets.

That is even more embarrassing as earwigs do have very interesting characteristics. Very outstanding is the - present probably in all species - the brood care by the mother for eggs and first instar larvae. Furthermore the earwigs' flight capability poses an interesting problem. Some specimens of one species do fly and sometimes caught with light traps, while other specimens of the very same species cannot fly at all. A systematic recording of the flight capabilities would be scientifically interesting and feasible for amateurs, too, who could collect the important biological basis data.

Worldwide about 2.200 species are known to science, Australia holds 88 species and in the range of the Fauna Europaea, 83 species are recorded.

The name 'earwig' is not quite understandable. Naturally earwigs do sometimes crawl into human ears, which they use as hiding place and retreat. Of course this happens in rural society which was interlinked with nature - for the good or bad - more intimately than our urbane societies. Earwigs use human ears as hiding place that is all. However this is also done by other insects, as was reported by South African doctors who found all sorts of insects in ears. Amongst them were cockroaches, bugs, beetles- however: no earwigs (use keyword 'medicine' in the 'Keywords' database). So it seems not really logic to me to name especially this insect earwig.

Incidentally, there seem to be only two ways how to name the Dermaptera. It is either after the human ear, as in English, German, French and Russian. In other languages such as Japanese, Thai, but also Swedish, Spanish, Finish, Italian and Portuguese the name refers to the cerci, regarding them as scissors or pincers or tongs (more in my database 'Vernacular, Native or Common Names').

However you call them, earwigs never purposefully crawl into the human or other animals ears' and never lay eggs there, and never build nests there or penetrates to the brain to lay eggs.
