Australian Tiger - Ictinogomphus australis

FAMILY LINDENIIDAE

This page contains pictures and information about Australian Tiger Dragonflies that we found in the Brisbane area, Queensland, Australia.
 
Male, body length 65mm
 
Australian Tigers are yellow and black in colour. The males are with broad flaps on clubbed abdomen end. Australian Tigers are common on large ponds and slow flowing waters.

We found Australian Tigers easily on Bulimba Creek and Moolabin Creek, the two sites that we visited most for dragonflies. The Australian Tiger always occupy the best perching position, which is usually the emergent vegetation or fallen branches in the pool or slow running water, where the dragonfly can oversee a large piece of water as his territory.

The Australian Tiger will drive away any intruders, i.e., another male of his own species. The Australian Tiger will ignore any damselfly and LIBELLULIDAE. If it is an Australian Emerald or Slender Tigerlet, the Australian Tiger may follow it for one or two meters to confirm it is not another Tiger. If it comes another male Tiger, the dragonfly will chase it and both will disappear from our eyes sight, and he will come back a few seconds later. If it is disturbed, such as come too close to take the photo, it flies away and seems never come back, or at least half  an hour, the longest time that we had waited.

The above pictures show the female Australian Tigers. Male and female look the same except the female has the thicker abdomen and round wings base. We saw female lays eggs by quickly dip her abdomen tip onto the water surface, closely guarded by a male.
 
Female hunts near ponds when not laying eggs.
