There is also the genual stage but no one ever really reaches that.

In the cricket Gryllus assimilis the sub genual organ fills up most of the tibia and has a fan-like shape.

The name Bug probably came from the old Germanic word baug-s which meant something winding, genual, bent (what was mentioned about river by Gervase of Tilbury who used latin term armilla).

Eupathidial setae are distinguished and denoted from setiform setae on the femoral, genual, fibial, and tarsal segments of the legs of a rhagidiid mite for the first time.
