Wanderings in a swamp.

I spent my lunchtime at work earlier this week traipsing through a great little wetland along the Bass Coast in SW Gippsland. The main reason was to ‘hunt’ down and photograph the elusive Swamp Skink Lissolepis coventryi which is currently listed as threatened under the Flora and Fauna Guarantee Act 1988Last year I came across a pair of these skinks and only managed a photo of the head of one of them so I was hoping to get a better one this time. The skinks tend to sun themselves on top of dense vegetation on the fringe of this small wetland but will scamper away at the slightest movement.

While waiting for the skinks to emerge into the full sun on top of a thicket of Prickly Moses Acacia verticillata and Coral Fern Gleichenia sp my eyes were diverted to several large iridescent blue-green beetles moving about on the Prickly Moses wattle. These turned out to be the famous Botany Bay Weevil Chrysolopus spectabilis. These are famous because they were one of the first insects to be collected in Australia when the Endeavour landed in 1770 in Botany Bay and it was named by Sir Joseph Banks. The skinks were a no-show so I decided to snap some pics of this beetle.

Some of these were in the process of mating while others were feeding on the new leaves of the Prickly Moses, wattles being their primary food.

Being summer the water in the central part of the wetland had receded and many of the wetland plants on the outskirts of the swamp were taking advantage of this and putting on new growth or flowering. The Large Tongue-orchid Cryptostylis subulata was one such plant.

This spectacular orchid, although not rare, is uncommon in areas of moist soil, particularly around wetlands. Tongue Orchids are pollinated by male Orchid Drupe Wasps Lissopimpla excelsa which confuse the shape and smell of the flower for a female wasp. The male subsequently tries to mate with it and in turn pollinates the flower. Several of these orchids were found but no wasps were seen, maybe next time I’ll get a photo.

So, although it’s a bummer about missing the Swamp Skink again, I did manage to find some interesting things on my half hour lunch break.
