The correct spelling of the insect commonly known as an "earwig" is often a source of confusion. The word is pronounced /ˈɪərwɪɡ/ (ee-er-wig) with two syllables, not "ear wig" as many people assume. This is because the word "ear" is actually a corrupted form of the Middle English word "ēare" meaning "ear," and "wig" comes from the Old English word "wicga" meaning "beetle." So, an earwig is actually a beetle that sounds like it lives in your ear!
An "earwig" is a noun referring to a small, elongated insect belonging to the order Dermaptera, characterized by thin, flexible pincers at the end of the abdomen. Its name is derived from a widespread, yet misinformed belief that it possesses a tendency to crawl into the human ear canal. With a size ranging between 5-25mm, earwigs typically have flattened bodies, a pair of large compound eyes, and short antennae. They are generally nocturnal creatures, seeking refuge in dark crevices during the day and emerging to forage for food during the night.
Despite the common myth regarding their fascination with ears, earwigs are, in fact, omnivorous insects feeding on a variety of small invertebrates, plant material, and occasionally, decaying organic matter. While they can occasionally be considered a garden pest due to their appetite for certain crops, earwigs are generally beneficial as they prey on insects harmful to plants, such as aphids.
In informal contexts, the term "earwig" can also be used as a verb meaning to influence or manipulate someone or to eavesdrop on a private conversation. In this sense, it typically implies a sly or underhanded method of gathering information or exerting control over a situation, reminiscent of an earwig's alleged tendency to invade ears.
The term "earwig" originated from Old English, where it was referred to as "ēarewicga".ēare meaning "ear" and wicga meaning "insect" or "beetle". The name likely derived from the mistaken belief that these insects had a tendency to crawl into people's ears. Although this is a common misconception, the term has persisted over time and eventually became known as "earwig".
