Looking much like most other male Orthetrums, Orthetrum boumiera (Brownwater Skimmer) is, nonetheless, a little more special. It is said to be confined to brown, acidic dune lakes with shallow margins. It is not widespread, being limited to northeastern New South Wales and southeast Queensland.
We had but one meeting at Poona Lake (near Rainbow Beach) after a 2km trek through forest in considerable heat. I have to say, having seen a less than common species, the effort was worth it.
The thorax is said to be almost uniformly dark, though on a mature male with pruinosity that doesn’t show, and there is a small dark spot at the baser of the hind-wings.
