Also Pomaderris pilifera subsp. talpicutica (with rounded, notched/obcordate leaf apex and a grey-green 
velvety upper leaf surface) identified and named by Mark who pointed out the differences in leaf shape 
and texture from Pomaderris pilifera subsp. pilifera which has a smaller, pointed leaf apex, called an 
apiculum and lacks a velvety upper leaf surface. Other interesting plants found were: Philotheca 
verrucosa , Spyridium eriocephalum, Clematis clitoroides and Daviesia ulicifolia subsp. ruscifolia. 
At lunch in Tommys Bight a dried specimen of the Big-bellied seahorse - Hippocampus abdominalis 
was discovered, as were live introduced seastars Asterias amurensis, and we were visited by Ichneumid 
wasps and a pair of hybrid mallard/black ducks. 
An enjoyable morning of discovery; good to be accompanied by the new generation of field naturalists. 
Finds included: 
Tasmanian grasshopper ( Tasmaniacris tasmaniensis), juvenile Gumleaf hopper (Goniaea australasiae) 
A number of wasps (ichneumid) and European, caterpillars and their nests, an excellent specimen of 
Zachria spenceri (huntsman look-alike spider) was found in rocks - interestingly, as ‘ Spiders of 
Tasmania’ reports it is ‘generally found only at high altitudes’ being common on Mount Wellington, 
Dry’s Bluff and Cumming’s Peak.

Snails, by Kevin Bonham 
East Risdon Reserve is not somewhere I expect to find much - in four previous visits to the area I've 
found only three species total - in one case I found nothing at all! The pattern of low diversity and low 
numbers continued on this trip with only two species found, but while one of them was the common 
Caryodes dufresnii , the other was a very welcome new record. I eventually managed to identify the 
crumpled remains of a small charopid as Roblinella sp. "Flagstaff, a species I discovered in 1998 and 
have only previously seen in an area of about 1.5 x 3 km around Flagstaff Hill, where it occurs in gullies 
very similar to the one draining into Tommys Bight. This second locality for the species extends its 
range by 5 km.
