Common NameSwamp Tigertail
FamilySynthemistidae
Genus/SpeciesSynthemis eustalacta (Burmeister, 1839)
Abundance &
Distribution
Common in New South Wales and Victoria from the Queensland border to Melbourne. Less common through western Victoria into South Australia as far as around Adelaide.
HabitatFound mostly at swamps and bogs at all altitudes.
DescriptionEyes are mostly green, the thorax is dark brown and black with yellow stripes and there are paired spots along the tail. In the male the abdomen is particularly slender and has a large pair of yellow spots near the end.
Similar SpeciesAlthough Synthemis eustalacta is very similar to Synthemis tasmanica, these species are geographically isolated from each other (the latter only appears in Tasmania). There is however another variant (or species) in western populations of the mainland that approaches Synthemis tasmanica. Larvae have been collected in the Grampians (G. Teischinger, pers. comm.) and I have photographed dark adults in Piccaninnie Ponds/Long Swamp complex (see these photos of a male and female. At these locations typical E. eustalacta have also been recorded. Its status is uncertain and more research is required.
It is also somewhat similar to Parasynthemis regina in that both species have a larger yellow section near the end of the tail.
Behaviour &
Observations
These perch hanging from vegetation but males will often be out on patrol over breeding habitat when the temperature is warm enough.
