The ground plan of the abdomen of an adult insect typically consists of 11–12 segments and is less strongly sclerotized than the head or thorax. Each segment of the abdomen is represented by a sclerotized tergum, sternum, and perhaps a pleurite. Terga are separated from each other and from the adjacent sterna or pleura by a membrane.

Adult insects are the only arthropods that ever have wings, with up to two pairs on the thorax. Whether winged or not, adult insects can be distinguished by their three-part body plan, with head, thorax, and abdomen; they have three pairs of legs on the thorax.

This ground louse is also notable because its spermatophore is only 0.1 millimetres (0.0039 in) long, among the smallest in the arthropod world but the single sperm it contains is 3 micrometres (0.00012 in) wide and 3 millimetres (0.12 in) long almost as long as the insect itself. [1]
Nemobiinae are typically small insects, generally less than 15 mm (0.6 in) long, and less robust than many other crickets (e.g. those in the Gryllidae). The thorax is densely bristled and the abdomen is also bristly. There are four (or sometimes three) pairs of long, movable spines above the tip of the abdomen.
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive).
Archaeognatha are small insects with elongated bodies and backs that are arched, especially over the thorax. Their abdomen ends in three long tail-like structures, of which the lateral two are cerci, while the medial filament, which is longest, is an epiproct. The tenth abdominal segment is reduced. [8] The antennae are flexible.
Apocrita is a suborder of insects in the order Hymenoptera.It includes wasps, bees, and ants, and consists of many families.It contains the most advanced hymenopterans and is distinguished from Symphyta by the narrow "waist" formed between the first two segments of the actual abdomen; the first abdominal segment is fused to the thorax, and is called the propodeum.
