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 ...

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 · Updated: May 21, 2024. Views: 10,915. 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.
Jan 1, 2015 · Fewer than 10,000 of these hexapod species are not insects. The group dates back at least to the protoinsects (e.g., Rhyniognatha hirsti Tillyard 1928) of 400 mya in the early Devonian period. Since that time, they have come to dominate the terrestrial environment and be important ecological players in inland water ecosystems.

Gonads and Gametogenesis in Arthropods. Romano Dallai, in Arthropod Structure & Development, 2014. 1 Introduction. Hexapoda are the largest and most diverse group of organisms. The species richness of the group has been determined by several factors, among which a relatively old origin, dating back to the lower Devonian (Pragian, 411–407 million years ago) (Whalley and Jarzembowski, 1981 ...
Caddisflies are moth-like hexapods that are attracted to light sources after dark. They inhabit freshwater rivers and lakes, where both caddisfly larvae and adults consume plant debris, algae, insects, and sometimes crustaceans. Caddisfly larvae are a favorite food for many fish species, particularly trout.

Oct 23, 2021 · We are taught from childhood that insects are the ones with six legs. However, that is not entirely true. Our world is heaving and wriggling with six-legged creatures that are not insects. The OTHER Hexapoda. The non-insect hexapods are called springtails, diplurans, and proturans. They don’t have external mouthparts, so are sometimes called ...
