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 considered insects: Collembola (springtails), Protura (coneheads) and ...

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...
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.
Jul 11, 2024 · Most other arthropods have more than three pairs of legs. Alternatively, the Hexapoda could be eliminated because they are polyphyletic, the Insecta promoted to sub-phylum, and the minor groups become incertae sedis. This is a Latin term meaning "of uncertain placement" and used for a taxonomic group when its broader relationships are unknown ...
Hexapods have three pairs of legs, situated in each one of the thoracic segments, from which comes the name of the group. There are certain exceptions, like the apodous larval forms and some adults with a specialized life form (e.g., adaptation to parasitism).
May 29, 2023 · The hexapoda have the head, thorax, and abdomen differentiated, and are mostly winged. They have three pairs of mouth organs , viz, mandibles, maxillae, and the second maxillae or labial palpi; three pairs of thoracic legs; and abdominal legs, which are present only in some of the lowest forms , and in the larval state of some of the higher ones.

Oct 31, 2023 · Arthropods include the Hexapoda (insects), the Crustacea (lobsters, crabs, and shrimp), the Chelicerata (the spiders and scorpions), and the Myriapoda (the centipedes and millipedes). Arthropods have a segmented body plan that contains fused segments divided into regions called tagma.
