This Photo:     🔍Pair Mating, 3 pronged clasp🔎

EXTRA - Photo Specific Information:
Why do male dragonflies have 3 prongs on the tail? Here's the answer: one over her face, and 2 behind her head (one each side of her neck). It can be a pretty violent affair where she can litterly loose her head!
General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills, the Riverland and elsewhere
Different to the Australian Emerald (H. australiae) in a few ways. The Tau has: 1. Orange leading wing veins & wing patch (pterostigma), rather than black 2. An orange spot at the end of it's tail (segment 10) 3. An inverted "T" on it's face (unfortunately we didn't capture this in the photo's, yet)
