Superfamily Forficuloidea

Forficuloidea is a major superfamily within the parvorder Eteodermaptera (Order Dermaptera), comprising many of the most familiar and widespread earwigs. Members of this superfamily occur worldwide and inhabit a wide range of environments, including forests, grasslands, agricultural fields, gardens, and urban areas. They are typically found in moist, sheltered locations such as leaf litter, beneath bark, under stones, and within soil crevices.

Earwigs of the superfamily Forficuloidea are generally small to medium-sized insects characterized by an elongated, flattened body and a distinctive pair of forceps-like cerci at the end of the abdomen. These cerci vary in shape among species and between sexes, often being more strongly curved in males than in females. They are used in defense, mating behavior, prey handling, and territorial interactions.

The head bears chewing mouthparts and long, segmented antennae. Most species are brown, reddish-brown, or dark-colored, providing camouflage in their natural habitats. Many possess short, leathery forewings that cover intricately folded membranous hind wings, although some species are flightless or have reduced wings.

Development occurs through incomplete metamorphosis, consisting of egg, nymph, and adult stages. Females often display a remarkable degree of maternal care, guarding eggs and young nymphs, cleaning the eggs to prevent fungal growth, and protecting offspring during early development.

Feeding habits are primarily omnivorous. Members of Forficuloidea consume decaying plant material, fungi, algae, seeds, fruits, and a variety of small invertebrates. Many species also prey on aphids, mites, and other soft-bodied insects, making them beneficial predators in gardens and agricultural systems.

The superfamily includes prominent families such as Forficulidae (common earwigs), which contains many of the best-known species.

Ecologically, Forficuloidea plays an important role in decomposition, nutrient cycling, and the natural regulation of small arthropod populations. They contribute to ecosystem balance as both scavengers and predators and serve as prey for birds, reptiles, amphibians, and mammals. Although some species may occasionally damage crops or ornamental plants, most are beneficial and valuable components of terrestrial ecosystems.
