Is Archaeognatha an insect?
Is Archaeognatha an insect?
Archaeognatha are small insects with elongated bodies and backs that are arched, especially over the thorax. They have three long tail-like structures, of which the lateral two are cerci, while the medial filament, which is longest, is an epiproct. The antennae are flexible.
How many species of thysanura are there?
370 species
Distribution. There are about 370 species of thysanurans worldwide.
What is the order of bristletails?
bristletail, (order Archaeognatha), any of approximately 350 species of primitive wingless insects that measure from 5 to 20 mm (0.2 to 0.8 inch) in length when they are fully grown and have three slender bristlelike appendages at the tip of the abdomen.
Do jumping Bristletails have wings?
Jumping Bristletails are small, jumping insects that have a hunched back like shrimp, but resemble a Silverfish with three ‘tails’ at the tip of the abdomen: one long, with two shorter ones on either side of it. They do not have wings, but can propel themselves into the air using the abdomen.
Where are Zygentoma found?
The Maindroniidae comprise three species, found in the Middle East and in Chile. The Protrinemuridae comprise four genera. Like Nicoletiidae species living in caves, they lack eyes.
What is the difference between bristletail and silverfish?
Silverfish and firebrats are insects referred to as bristletails because they both have “bristle-like” extensions on their hind end. Silverfish have a body shape that resembles a teardrop, are covered in metallic-looking scales and long antennae. Silverfish are wingless and move rapidly in a “fish-like” motion.
What insects are in the thysanura?
Thysanura are primitive but well-adapted to survive in domestic environments such as basements and attics. They are nocturnal scavengers or browsers, hiding under rocks or leaves during the day….

Where do you find bristletails?
HABITAT. Bristletails are found on the soil, in leaf litter, under rocks, and on stumps and logs from sea level to 15,750 feet (4,800 meters) in the Himalayas. Species living in tropical rainforests often spend some or all of their time high up on the trunks and limbs of trees.
Do firebrats jump?
Watch for them to “run fast” when threatened; they also jump sideways. Firebrats prefer a drier habitat than silverfish.
How do silverfish jump?
As their name suggests, they jump—six inches and more—which silverfish can’t do. This they accomplish by pushing up with their legs while contracting the muscles in their abdomen to arch their body downward. They can run fast, too.
What is the family of Zygentoma?
The Zygentoma comprise 5 families and some 400 species in about 90 genera. 1. Lepismatidae This largest family includes the well-known silverfishes, some of which occupy human houses. This family is the richest in genera (more than 21) and species (>200).
What are the characteristics of Microcoryphia?
Insects in the Order Microcoryphia (also called Archaeognatha) are elongate, wingless with a pair of antennae. At the end of the abdomen they have two cerci and a central caudal filament.
What is the scientific name for a Microcoryphia?
However, more recently they have been recognised as a different insect order within the Apterygota. The scientific name for the order – Microcoryphia – comes from the Greek micro (small) and coryphia (head) and they do have rather small heads in front of a large pronotum.
Are silverfish and Microcoryphia the same?
Members of the order Microcoryphia, or Archaeognatha, are superficially similar to common silverfish (order Thysanura). Both have life cycles without metamorphosis and never develop wings. Microcoryphia are true insects, but they diverged from the main developmental path leading to other insect orders very early in evolutionary time.
Is Archaeognatha the same as Microcoryphia?
Archaeognatha (Order: Microcoryphia) However, more recently they have been recognised as a different insect order within the Apterygota. The scientific name for the order – Microcoryphia – comes from the Greek micro (small) and coryphia (head) and they do have rather small heads in front of a large pronotum.
