The Macalister River, or Wirnwirndook’yerun as it was known to the first people, runs through the Bellbird Corner Riverside Reserve. Over twenty years this small area has been transformed from grazing land to a biodiverse nature reserve, in a partial return to its thickly wooded state of seventy five years ago. The river has seen good flows come downstream recently, and two species of Persicaria have taken advantage of high water levels and put on luxuriant growth.


The two species are Water Pepper, P. hydropiper, and Slender Knotweed, P. decipiens. Both are flowering now, and the white and pink flowers are a valuable resource for native bees that are in the midst of their breeding cycle. Leioproctus cristatus has been observed there for years, but at the moment they are in numbers exceeding anything previously seen.


While photographing these, another small bee appeared and landed. A breeze moving the plants made the job hard, but one shot was obtained for identification purposes. After searching without success it was handballed to Mitch of Woolenook Native Nursery who came through with the goods, the Honey-headed Masked Bee, Hemirhiza melliceps.

A return trip managed another shot when it again appeared around midday.

The literature states that this is a bee of wet forests in Southern Queensland and Eastern New South Wales, and a search on iNaturalist found just one previous Victorian record, near Cooper’s Creek in January 2017. This is a special reward for twenty years of dedicated volunteer work.
Environmental flows overseen by the West Gippsland Catchment Management Authority improve river health, enhance aquatic diversity and native fish populations, and sustain riparian vegetation such as the Persicaria.
Dead Silver Wattles, riddled with holes, are left in situ for the native bees and other insects that utilise the holes for nesting chambers, and the undisturbed ground offers a safe haven for the bee species that dig burrows for their nests. Now, more than ever, we need habitat protection and restoration for the well being and long term future of so much of our Australian flora and fauna, and Bellbird Corner Riverside Reserve is playing its part in a small but significant way.
