THYSANURA

The Thysanura is a sub-order of Apterygota, minute wingless insects of which five species occur in Britain. The Thysanura are found in damp earth, in rotten wood, and among other decaying vegetable matter. They are covered either with hairs or scales. There is no metamorphosis, the young hatching from their egg in the adult form. They have long, many-jointed antennae apparently at both ends. The Thysanura includes the Bristletail.
