The
order Embioptera, commonly known as
webspinners, are a small group of mostly
tropical and
subtropical insects, classified under the
subclass Pterygota. The order has also been referred to as
Embiodea or
Embiidina. The name Embioptera ("lively wings") comes from
Greek, εμβιος,
embios meaning "lively" and πτερον,
pteron meaning "wing", a name that has not been considered to be particularly descriptive for this group of fliers, perhaps instead referring to their remarkable speed of movement both forward and backward. The group probably first appeared during the
Jurassic and is well represented in
Cretaceous amber. The common name
webspinner comes from the insects' unique ability to spin
silk from structures on their front legs. They use the silk to make a web-like pouch or gallery in which they live.
