What is Apterygota and example of it?
The name Apterygota is sometimes applied to a subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and in their evolutionary history; notable examples are the silverfish, the firebrat, and the jumping bristletails.
Which order is Apterygota?
Orders in the Subclass Apterygota: Diplura – diplurans (Entognatha) Protura – proturans (Entognatha) Collembola – springtails (Entognatha) Thysanura – silverfish and firebrats (Insecta)
Are silverfish Apterygota?
The term apterygote, therefore, is sometimes applied only to those groups thought to be ancestors of pterygotes—i.e., the silverfish, fishmoths, and firebrats (order Zygentoma) and the bristletails (order Archaeognatha), together with the extinct monurans (order Monura).
How many orders are Apterygota?
In the past, entomologists grouped all primitive apterygote insects into a single order (Thysanura). More recently, however, the trend has been to divide this subclass into three orders: Archaeognatha, Thysanura, and Monura.
Does Apterygota bite?
Apterygota (Ametabola; subphylum Uniramia, class Insecta) The smaller subclass of insects, containing two orders (Archaeognatha and Thysanura), whose members are primitively wingless (in contrast to secondarily wingless insects, e.g. fleas, lice, etc.), terrestrial insects with ectognathous, biting mouth-parts.

What are Apterygota (wingless insects)?
Apterygota (wingless insects) hatch from their eggs in a form very similar to the adult, and just grow from being mini versions of the adults to the real thing. This type of development is called ametaboly or incomplete metamorphosis. These are very small insects – smaller than 2 cm – so you will need a hand lens or magnifier to see them properly.
What are the appendages of apterygote insects?
Second, apterygote insects have short, segmented appendages along the sides of the abdomen. These structures appear to be homologous with abdominal appendages of crustaceans.
What are the three orders of apterygote?
More recently, however, the trend has been to divide this subclass into three orders: Archaeognatha, Thysanura, and Monura. Of these, only Archaeognatha and Thysanura have survived to the present time. These apterygote orders share several “primitive” characteristics with crustaceans and non-insect hexapods.
