3. Dragonflies. A dragonfly | Image by liggraphy from Pixabay. 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.
- Mayflies. Mayflies are small hexapods that are not only active during May but can also be found throughout late spring and summer. These one-inch creatures play a crucial role in the ecosystem as a valuable food resource for reptiles and fish.
- Springtails. Springtails are wingless hexapods known for their ability to jump several inches from one spot to another. They are tiny insects, measuring less than 1/8th of an inch in length, and come in colors like black, brown, white, or brightly colored.

- Damselflies. Close cousins of dragonflies, damselflies resemble dragonflies but have thin, long abdomens and two pairs of wings. They are often brilliantly colored, reflecting iridescent shades of red, green, and blue.
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 ...

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.
Like all arthropods, insects have segmented bodies, jointed appendages, and an exoskeleton made mostly of chitin. As members of the subphylum Hexapoda, insects have six legs. They also have additional appendages that are modified for other functions, and we will look at these in more detail in the Insects: Structure and Function (Advanced) concept.
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.

What is a Hexapoda and a Crustacea?
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). The locomotor appendage, basically adapted to walking on the ground, is formed by one ...
