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.
