Lake Fenton Trapdoor Spider

Plesiothele fentoni

The Lake Fenton Trapdoor Spider is not a pest but a species of significant scientific and conservation interest. It is considered a 'living fossil', representing an ancient lineage of spiders that dates back to the time of the Gondwanan supercontinent. This species is found only in a very small, specific high-altitude area of Mount Field National Park in Tasmania. It is a classic trapdoor spider, living a sedentary life in a silk-lined burrow sealed with a thick, plug-like lid. Due to its extremely limited distribution and scientific importance, it is a protected species. It poses no threat to humans and encounters are exceptionally rare.
