The insects of the order may be called bristletails, from their three long caudal filaments. The families Machilidae and Meinertellidae of the jumping bristletails were once included with Thysanura, but are now in the order Archaeognatha (= "Microcoryphia"). Occasionally, the correspondingly restricted order Thysanura is referred to as Zygentoma.Hi ppl,my name is William Zhang Download high resolution version (362x735, 88 KB)Copied from the German wiki. ...

Silverfish are so called due to the silvery glitter of the scales covering their bodies. Their movement is "fish-like" and makes it look as if they're swimming. They are less than half an inch (1 cm) long and found in damp corners or amongst books and paper in houses. Silverfish feed on cereals, paste, paper, starch in clothes, rayon fabrics and dried meats. ^[1]Silverfish can sometimes be found in bathtubs or sinks at night, as they have difficulty moving on smooth surfaces and so become trapped. Wild species often are found in habitats such as caves, and some are commensals living in association with ant colonies. Glitter is the word used to describe an assortment of very small (roughly 1 mm²) pieces of paper, glass or plastic, used for various functions in art, craft, and design. ...

There are no current species formally considered to be at conservation risk, though several are troglobites limited to one or a few caves or cave systems, and these species run an exceptionally high risk of extinction. In archaeology, a troglodyte is any member of a primitive tribe of cave-dwelling people (from the Greek troglodytai, from trogle, a hole and dyein, to enter). More recently troglodyte is used to describe a technophobic person; i. ...
