Earwigs make up the insect order Dermaptera and are found throughout the Americas, Africa, Eurasia, Australia and New Zealand. With about 2,000 species in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps-like pincers on their abdomen, and membranous wings folded underneath short forewings, hence the scientific order name, “skin wings”. Some groups are tiny parasites on mammals and lack the typical pincers. Earwigs rarely use their flying ability. (source)
