Hexapoda. The subphylum Hexapoda (from Greek for 'six legs') or hexapods comprises the largest clade of arthropods and includes most of the extant arthropod species. It includes the crown group class Insecta (true insects), as well as the much smaller clade Entognatha, which includes three classes of wingless arthropods that were once ...
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. However, there is some evidence that ...
Hexapoda is the largest subphylum within the phylum Arthropoda in terms of described species, if not actual numbers (some arachnologists contend that the free-living and parasitic mites are more diverse, but no one knows for certain). Roughly one million hexapod species have been described from terrestrial and aquatic habitats.

Mayflies are not only active during May but throughout late spring and summer, providing a valuable food resource for reptiles and fish. Brown, yellow, or gray in color and possessing thin, long abdomens, mayflies are small, one-inch hexapods that prefer to live near clean lakes and streams. In fact, ecologists often gauge mayfly populations to det...
Wingless hexapods that can be black, brown, white, or brightly colored, springtails resemble fleas in their ability to jumpseveral inches from one spot to another. Tiny insects (less than 1/8th inch long) with elongated bodies, springtails thrive in moist environments and are important decomposers of decaying plant and soil detritus. Immature sprin...
Dragonflies can be seen hovering and zipping around everywhere in the world except Antarctica. With their large, often colorful bodies, long wings, and oversized eyes, dragonflies are one of the most recognizable hexapods gracing ponds, lakes, and streams. They have the amazing ability to fly as fast as 35 miles per hour forward and backward. Drago...
Antlions earned their name due to the rapacious nature of antlion larvae. Little antlions dig small pits in sandy ground that effectively trap ants and similar insects. After hiding themselves underground at the bottom of the pit, antlion larvae wait patiently for an insect to fall into the trap. They then enjoy a delicious meal without leaving the...
Mothlike in their appearance and attraction to light sources after dark, caddisflies live around freshwater riversand lakes where caddisfly larvae and adults consume plant debris, algae, insects, and sometimes crustaceans. Immature caddisflies are a favorite fish food, while trout specifically are enticed by flying adult caddisflies. The artificial...
Hexapod. In subject area: Immunology and Microbiology. 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.
The first known hexapod, Rhyniella praecursor, is a collembolan from the early Devonian of the Rhynie Chert in Scotland (dated 407−396 million years before present), described in 1926. In the same deposition, slightly younger, remains have been found that were assigned to an ectognathic (winged) insect, Rhyniognatha .

Oct 31, 2023 · Subphylum Hexapoda. The name Hexapoda denotes the presence of six legs (three pairs) in these animals, which differentiates them from the number of pairs present in other arthropods. Hexapods are characterized by the presence of a head, thorax, and abdomen, constituting three tagma. The thorax bears the wings as well as six legs in three pairs.
