Hexapods are named for their most distinctive feature: a three-part body plan with a consolidated thorax and three pairs of legs. Most other arthropods have more than three pairs of legs. [5] Most recent studies have recovered Hexapoda as a subgroup of Crustacea. [6]

The only habitats that hexapods avoid are sub-tidal marine areas, such as oceans and shallow seas. The success of hexapods in colonizing land can be attributed to their body plan (especially the strong cuticles covering their bodies that provide protection from predators, infection and water loss), as well as their flying skills. Another successful...
Hexapods are vital to the communities in which they live; for example, early two-thirds of all flowering plant species rely on hexapods for pollination. Yet hexapods also pose many threats. These small arthropods can inflict vast crop damage and are known to spread numerous debilitating and fatal diseases in humans and other animals. The body of a ...
The thorax consists of three segments, the prothorax, the mesothorax, and the metathorax. Each segment of the thorax has a pair of legs, making for six legs in all (the forelegs, the middle legs, and the hind legs). Most adult insects also possess two pairs of wings; the forewings are located on the mesothorax and the hind-wings are attached to the...
Although most adult hexapods have wings, some species are wingless throughout their life cycles or lose their wings after a certain period before adulthood. For example, parasitic insect orders such as lice and fleas no longer have wings. Other groups, such as the Entognatha and Zygentoma, are more primitive than classic insects; not even the ances...
Hexapods are classified within the following taxonomic hierarchy: 1. Animals> Invertebrates > Arthropods > Hexapods Hexapods are divided into the following basic groups: 1. Insects (Insecta):There are more than one million species of insects that have been identified, and scientists estimate that there may be many millions more species yet to be na...

In many groups, the overall body form is solid, flattened, and compact, allowing beetles to hide easily, penetrate cryptic habitats, and even to burrow extensively in soil. Although some beetles have secondarily evolved softened or even greatly reduced elytra, there is no doubt that this modification has allowed beetles to become the preeminent ...
Hexapods are a well-established monophyletic group, based on the presence of three major body divisions—head, thorax, abdomen—and a single pair of locomotory appendages on each thoracic segment. From: Encyclopedia of Biodiversity (Second Edition), 2001
May 21, 2024 · Hexapods, subphylum Hexapoda, is a group of arthropods that includes the insects and some close relatives, including springtails, proturans, and diplurans. Hexapods are probably monophyletic, meaning they all descend from a common ancestor, and include no members that didn't descend from that ancestor.
May 29, 2023 · Hexapoda. (Science: zoology) The true, or six-legged, insects; insects other than myriapods and arachnids. The hexapoda have the head, thorax, and abdomen differentiated, and are mostly winged.
As the name indicates the Hexapoda have six legs, one pair per thoracic segment. The body segments are fused into three body regions: a head, thorax, and abdomen.. A single pair of preoral antennae are present. The waxy epicuticle protects against desiccation.
