The thorax is greenish to greyish yellow with black markings. The abdomen is black with pale yellow or pale green markings. Orthetrum serapia appears very similar to Orthetrum sabina and can be confused where the range of the two overlap in north-eastern Australia.

Zosis geniculata sometimes referred to as the humped spider or grey house spider, is a cosmopolitan species with a pantropical distribution. In Australia, it is often seen in buildings near human habitation.

A curve postmedial line found, which is almost always met by an oblique streak from apex. Hindwings orange, with a large black lunule beyond lower angle of cell. There is a marginal black band with cilia pale spots runs from costa to vein 2. Ventral side of forewings with orange postmedial band. The wingspan is about 90–110 mm in female. Female has much more variegated and dark reddish brown striated forewings. Reniform dark and sending a spur along median nervure to below the orbicular speck.

The adult is 2 - 2.5 cm long and 7 - 10 mm wide, stout, and grey to brown with a clear saltire in cream or yellow on its back.

The hindmost legs are much thicker than the other legs, and the hind femur has inner rows of fine teeth and one preapical spine. The hindmost legs are shorter and much swollen in the male. The hind tibia are inwardly lamellate in about middle third; less so in the male, which also has a distinct spine on the lamellate area. Later instar nymphs have a pair of orange spots in the middle of the upper surface of abdomen, and wing pads in later instars are marked with orange.
