The Entomobryomorpha are one of the three main groups of springtails (Collembola), tiny hexapods related to insects. This group was formerly treated as a superfamily, the Entomobryoidea. They can be best distinguished from the other springtail groups by their body shape. The Symphypleona are very round animals, almost spherical.
Springtails (class Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects.Although the three lineages are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts.
The Entomobryoidea are a superfamily of springtails (Collembola), tiny hexapods related to insects. In the modern sense, this group is placed in an order called Entomobryomorpha. This superfamily contains very characteristic species of springtails. They typically possess long legs and antennae, as well as a well-developed furcula.
The furcula is the "spring" for which the Collembola are given the name springtails. Proturans, sometimes referred to as "coneheads", do not have eyes or antennae. They possess a telson and abdominal styli thought to be vestigial legs. Diplurans have a pair of caudal cerci, from which their name, meaning "two-tailed", is derived. They also ...
Entomobryidae, sometimes called "slender springtails", is a family of springtails characterised by having an enlarged fourth abdominal segment and a well-developed furcula. Species in this family may be heavily scaled and can be very colourful.
The order Diplura ("two-pronged bristletails") is one of three orders of non-insect hexapods within the class Entognatha (alongside Collembola (springtails) and Protura). [3] The name "diplura", or "two tails", refers to the characteristic pair of caudal appendages or filaments at the terminal end of the body.
Tömösváry organ (arrow) on the head of a symphylan, just behind the base of an antenna. Tömösváry organs, also known as temporal organs or postantennal organs [1] are specialized paired sensory organs found in certain groups of myriapods (e.g. centipedes and millipedes) and hexapods (e.g. springtails), located on the head near the base of the antennae.
Hypogastrura nivicola is a species of dark blue springtail. Its English name in the United States is snow flea , but there are also additional springtails [ 1 ] (and insects) called by that name. They are often seen jumping about on the surface of snow on a warm winter's day in North America.
