The endangered McCubbin's caddisfly (Taskiria mccubbini) and Lake Pedder caddisfly
(Taskiropsyche lacustris) have recently been recollected from the Lake Pedder
area. Both species (family Kokiriidae) were first found at the original Lake Pedder
in 1965 but had not been collected since, despite targeted searches.
The rediscoveries were made by Brett Mawbey and myself from the Inland Fisheries
Commission while doing summer survey work for threatened caddises in the
World Heritage Area, with funding from the WHA Zoologist. The two males of T.
mccubbini were found in a sample taken in November 1998 using an automatic UV
light trap set on the shore of Lake Pedder below Coronation Peak. A single male of
T. lacustris was collected in January near Ted's Beach. Identifications were made by
David Cartwright in Melbourne and confirmed by Dr Arturs Neboiss, who originally
collected and described the species.
In total 87 species were identified among ca. 4500 specimens collected. Another
threatened species collected was the spotted microcaddisfly (Orphninotirchia maculata)
and there are tentative identifications of Diplectrona ?lyella and Hydrobiosella ?
armata. Our knowledge of the distribution of all the species collected has been
greatly increased.
