Similar species: Similar to H. tau which differs in having a distinct yellow spot on the tail tip, T-shaped mark on the face, orange veins on the leading edge of the wings and brown pterostigma. Differs from P. jacksoniensis which lacks the crescent-shaped marks curving inward over the abdomen.


Behaviour: Flies low over water, hovering stationary for periods and conducting sorties mostly close to the bank but occasionally out across open water. May be seen far from water hawking above head height over bare ground in gardens and parks.


Distribution: Widespread throughout Victoria but only recorded at altitudes less than 800m.


Australian State distribution (from CSIRO Entomology)


Habitat: Any standing water.
