Fat-bellied Emerald, Clubbed
Emerald, Broad-tailed Emerald
- Hemicordulia continentalis,
female, male, body length
- The Clubbed Emerald Dragonflies are medium in size, body length about 40mm. When we took those
pictures, we through they were Australian Emerald, another Emerald dragonfly species
which is common in Brisbane. Fat-bellied Emeralds can be
distinguished from other Emerald dragonfly species by the male's
strongly club-shaped abdomen. More information and pictures please click here.
- Tau, Emerald, T-mark Emerald
- Hemicordulia tau, body length 50mm
- The dragonfly's body is yellow in colour with black pattern. They look very similar to another Emerald species Australian
Emerald. They can usually be found in the same place. Because both of them
never rest, it is difficult to distinguish between them. The second
picture shows the close look of the dragonfly's face. Notice that when look
at its face from its front, the is the inverse black 'T' mark on its 'nose'.
This is why they are call T-Mark Emerald. More information please click here.
