Hexapods have bodies ranging in length from 0.5 mm to over 300 mm which are divided into an anterior head, thorax, and posterior abdomen. [7] [8] The head is composed of a presegmental acron that usually bears eyes (absent in Protura and Diplura), [9] followed by six segments, all closely fused together, with the following appendages:
As the name would suggest, members of Class Hexapoda have six (“hex”) legs (“poda”). Class Hexapoda has two major subclasses: Entognatha and Ectognatha; hexapods with enclosed mouthparts and hexapods with exposed mouthparts, respectively. Class Insecta belongs to the Class Ectognatha (exposed mouthparts).
The Hexapoda have six legs (three pairs) as their name suggests. Hexapod segments are fused into a head, thorax, and abdomen (Figure 15.20). The thorax bears the wings and three pairs of legs. The insects we encounter on a daily basis—such as ants, cockroaches, butterflies, and bees—are examples of Hexapoda.

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...
