Earwigs are elongated, nocturnal insects belonging to the order Dermaptera. Recognizable by their pincers (cerci) at the rear, these insects are often found in damp environments, such as gardens and under leaf litter. While they primarily feed on decaying plant material and other small insects, they are commonly misunderstood; contrary to popular belief, earwigs do not enter human ears. Although they can occasionally be a nuisance in gardens, they are generally harmless and play a role in the ecosystem by aiding in decomposition.

History of Earwigs

Earwigs have a long evolutionary history, dating back to over 250 million years, making them one of the older insect groups. Fossil evidence shows that these insects have changed little over millions of years, indicating their successful adaptation to various environments. Traditionally, earwigs were feared due to myths suggesting they would crawl into human ears while sleeping; however, these claims have been debunked. Earwigs are found globally, with many species adapting to different climates and habitats, including gardens and urban areas.

Key Historical Points:

Evolved over 250 million years ago, showcasing successful adaptation
Fossil records indicate minimal evolutionary changes over time
Myths about earwigs crawling into ears have contributed to their negative reputation
