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: Segment I ...
Jul 31, 2022 · 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. Many of the common insects we encounter on a daily basis—including ants, cockroaches, butterflies, and flies—are examples of Hexapoda.
Arthropods range in length from about 1 millimeter to 4 meters (about 13 feet). They have a segmented body with a hard exoskeleton. They also have jointed appendages. The body segments are the head, thorax, and abdomen (see Figure below). In some arthropods, the head and thorax are joined together as a cephalothorax. Arthropod Body Plan.
- 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.
- Dragonflies. One of the most recognizable hexapods, dragonflies can be found hovering and zipping around ponds, lakes, and streams worldwide, except in Antarctica.
- 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.
