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.
