The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind.

Cervix (insect anatomy)

The cervix in insects is a membrane that separates the head from the thorax and is composed of structures from both of these.

Insect wing

Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly.

The mesosoma is the middle part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the metasoma.

The mesothorax is the middle of the three segments in the thorax of an insect, and bears the second pair of legs.

The metathorax is the posterior of the three segments in the thorax of an insect, and bears the third pair of legs.

Mosquitoes are small, midge-like flies that constitute the family Culicidae.

Odonata is an order of carnivorous insects, encompassing the dragonflies (Anisoptera) and the damselflies (Zygoptera).

Pleuron (insect anatomy)

The pleuron (pl. pleura, from Greek side, rib) is a lateral sclerite of thoracic segment of an insect between the tergum and the sternum.

The propodeum or propodium is the first abdominal segment in Apocrita Hymenoptera (wasps, bees and ants).

The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs.

Scutellum (insect anatomy)

The scutellum is the posterior portion of either the mesonotum or the metanotum of an insect thorax; however, it is used almost exclusively in the former context, as the metanotum is rather reduced in most insect groups.

Tagma (biology)

In biology a tagma (Greek: τάγμα, plural tagmata – τάγματα) is a specialized grouping of multiple segments or metameres into a coherently functional morphological unit.
