Earwigs

Earwigs is the common name given to the insect order Dermaptera characterized by membranous wings folded underneath short leathery forewings (hence the literal name of the order—"skin wings"). The abdomen extends well beyond the wings, and frequently, though not always, ends in a pair of forceps-like structures termed cerci. The order is relatively small among Insecta, with about 1,800 recorded species in 10 families. Earwigs are, however, quite common globally. There is no evidence that they transmit disease or otherwise harm humans or other animals, despite their nickname pincher bug.

Etymology
Earwig is derived from Old English ēare "ear" and wicga, "insect". (Wicga is in turn related to wiggle, and ultimately to other words implying movement, including way and vehicle, all from PIE *wegh-.) The name comes from the old wives' tale that earwigs burrow into the brains of humans through the ear and therein lay their eggs.[1] Earwigs are omnivores that are predisposed to hiding in warm humid crevices and as such one may crawl into a human ear canal. This is not, however, a location where they are frequently found.

Appearance and behaviour
Two earwigs from Australia compared to a CF card—63 mm.Most earwigs are elongated, flattened, and are dark brown. Lengths are mostly in the quarter- to half-inch range (10–14 mm), with the Saint Helena Giant Earwig reaching three inches (80 mm). Cerci range from nonexistent to long arcs up to one-third as long as the rest of the body. Mouthparts are designed for chewing, as in other orthopteroid insects. Flight capability in Dermaptera is varied, as there are species with and without wings. In those earwigs that have wings (are not apterous), the hindwings are folded in a complex fashion, so that they fit under the forewings. Most species of winged earwigs are capable of flight, yet earwigs rarely fly around.

Most earwigs found in Europe and North America are of the species Forficula auricularia, the European or common earwig, which is distributed throughout the cooler parts of the northern hemisphere. This species feeds on other insects, plants, ripe fruit, and garbage. Plants that they feed on typically include clover, dahlias, zinnias, butterfly bush, hollyhock, lettuce, cauliflower, strawberry, sunflowers, celery, peaches, plums, grapes, potatoes, roses, seedling beans and beets, and tender grass shoots and roots; they have also been known to eat corn silk, damaging the corn. Typically they are a nuisance because of their diet, but normally do not present serious hazards to crops. Some tropical species are brightly colored. Occasionally earwigs are confused with cockroaches because of their cerci and their long antennae.

Earwigs are generally nocturnal and can be seen patrolling household walls and ceilings. Interaction with earwigs at this time results in a defensive free fall to the ground below, and the subsequent scramble to a nearby cleft or crevice.

Earwigs are also drawn to damp conditions. During the summer, they can be found around sinks and in bathrooms. Earwigs tend to gather in shady cracks or openings or anywhere that they can remain concealed in daylight hours. Picnic tables, compost and waste bins, patios, lawn furniture, window frames, or anything with minute spaces (even artichoke blossoms) can potentially harbor these unwanted residents. Upon gaining entry to the basement and living areas of the home, earwigs can easily find cover in undisturbed magazine and newspaper piles, furniture/wickerwork, base boards, carpeted stairways, pet food dishes, and even inside DVD cases and keyboards. Earwigs are exploratory creatures and are often found trapped in poison baited cups or buckets of soapy water.
