Order: Archaeognatha (bristletails)

A bristletail photographed on the ground in Cape indigenous evergreen forest.

Members of this small group of primitive-looking insects look similar to fishmoths (Thysanura) in that they are elongate, wingless and have three long filaments (a median caudal filament and two lateral cerci) sticking out the end of the abdomen. However, they can be distinguished easily in the field from fishmoths by a more dome-shaped, not flattened, body; the legs do not protrude far from the body and the cerci at the back are much shorter than the median caudal filament and kept close together along the line of the body axis, not spread out. They can jump by snapping the abdomen down quickly.

They feed on algae, lichens and vegetable debris. Eggs are laid in batches of in crevices. The larvae are like miniature adults.
