Number 16 was a wild female trapdoor spider from Western Australia, born around 1972 or 1973, who lived to be about 43 years old. She was the subject of a long-term monitoring project by arachnologist Barbara York Main, who studied her and other spiders for over four decades. Number 16’s death in 2016 gained widespread attention when it was discovered she was killed by a parasitic wasp. Main’s dedication to this project delayed her retirement, and she now resides in a care facility for Alzheimer’s. The story of Number 16 sheds light on the fascinating lives of trapdoor spiders and the dedication of researchers like Main and Leanda Mason.
