Hemigomphus cooloola (Wallum vicetail) favours sandy, sluggish streams and lakes. The common name features an uncommon word so I’ll attempt a brief explanation of wallum. Wallum country is an Australian habitat peculiar to coastal southeast Queensland, though it apparently does extend into northern New South Wales. This character is limited to it, hence the name.
Probably the prize of our 2019 Queensland excursion, one of our number went overboard (almost literally, wading up to his crotch) to find this handsome male H. cooloola. He found it at Seary’s Creek near Rainbow Beach, though you do have to go there when other folks are not using the habitat as a swimming hole.
