An overview of the Tasmanian geometrid moth fauna (Lepidoptera: Geometridae) and its conservation status


A brief review of the geometrid fauna of the large island of Tasmania and a simple analysis of its conservation status and threats are presented. The fauna comprises 310 species of which Ennominae contribute slightly less than half the total and Larentiinae one third; 23% of the geometrid fauna is endemic at species level. Mixed eucalypt-rainforest is identified as the richest wet forest habitat in geometrid species. Using distribution data at 10  km resolution, the most widespread and most restricted taxa are identified. The conservation status of Lepidoptera living above 800 m is relatively good. However, coastal species and those associated with herb-rich native grasslands are under some pressure from habitat change. Three species of geometrid moths are listed as threatened in Tasmania’s Threatened Species Protection Act 1995 but several others may qualify for listing.
