Common NameEastern Swamp Emerald
FamilyCorduliidae
Genus/SpeciesProcordulia jacksoniensis (Rambur, 1842)
Abundance &
Distribution
Moderately common but localised from the Queensland border to near Adelaide, including Tasmania.
HabitatFound in relatively clean permanent to ephemeral swamps at all altitudes, less so along slow flowing rivers.
Description &
Identification
Males and females have similar colors and patterns that features a predominantly pale head and thorax with some black infusion. Eyes are usually green in mature males but usually golden in females. The abdomen (tail) features a thick, black dorsal band virtually all its length, broken by pale sections between the segments. The side of the abdomen is golden yellow with two diagonal, dark lines (without any significant curvature).
Similar SpeciesVery similar to Procordulia affinis, which is restricted to southern Western Australia but is dark between the abdominal segments. Most similar to Hemicordulia australiae, which features similar coloration (including green eyes) but the pale abdominal markings on the side, like that of Hemicordulia tau, are distinctly curved upwards near the front of most segments. Other Hemicordulia species within the range have more significant yellow markings on the abdomen.
Behaviour &
Observations
On warm days males tend to spend their entire time patrolling about a metre above the water level. This species tends to perch vertically from vegetation, usually 1–2 metres above the ground or water level.
