26 December 2013
Started the day in Long Swamp (Discovery Bay Coastal Park) but it was overcast and still quite cool
so I decided to walk further along the track than I'd been to see if the swamp was accessible
(it does look interesting on satellite imagery).
Amazingly, the first time I went off the track and looked over the dunes the swamp was there
at the base of the hill before me with little more than relatively sparse Coast Wattle Acacia longifolia
in the way.
Since I had walking shoes on I had to wade into the swamp bare-foot, often damgerous because of the
usual presence of large Tiger Leeches Richardsonianus australis
I was however fortunate that in this swamp I only encountered a few small individuals so wasn't overwhelmed.
The first interesting species I encountered were numerous red Austrothemis nigrescens
This is a rare species in Victoria and, although I have seen numerous individuals in other parts of Long Swamp on previous visits,
I had never come across a vibrant red, mature male like I suddenly saw numerous of here.
Most interesting was that soon after nearing a more opean area of the swamp (with deeper water) I encountered my first
of several Austroagrion cyane
Primarily a species known from southern Western Australia, these had never previously been recorded in Victoria.
They had long been suspected of being somewhere in the west of the state,
with several records from South Australia over the years and I had seen them at Piccaninnie Ponds
(my only previous encounter) three years earlier
And I didn't just see one, there were quite a few about and this would appear to be there local stronghold.
