''Hapljapyx'' is a genus of

diplura The order Diplura ("two-pronged bristletails") is one of three orders of non-insect hexapods within the class Entognatha (alongside Collembola (springtails) and Protura). The name "diplura", or "two tails", refers to the characteristic pair o ...

Japygidae thumb The japygids (family Japygidae) are a taxon of hexapods, of the order Diplura, commonly known as forcepstails. In this family, the paired cerci at the end of their abdomens are pincer-like (superficially similar to the unrelated earwig ...

where the male deposits a spermatophore on the ground. This is taken up by a female, who then lays her eggs in clumps in rotting vegetation or in crevices in the soil. Some species are known to guard their eggs and young. Young diplurans resemble adults. Moulting continues throughout life and an adult may moult up to 30 times during its lifespan of about a 1 year. Hapljapyx are predatory carnivores and use their cerci to capture prey.
