Researchers at the Natural History Museum in London describe a new parasitic wasp from the museum’s collections, naming it in honour of Sir David Attenborough’s 100th birthday on 8 May. The specimen was collected in Chile’s Valdivia province in the early 1980s and had been stored in an unsorted drawer for more than four decades. Recently, a volunteer noticed the specimen and researchers examined it closely, confirming it is new to science. Sources report the wasp represents both a new species and a new genus. The wasp is named Attenboroughnculus tau. The discovery is presented as part of a wider set of tributes marking Attenborough’s influence on natural history, conservation, and public understanding of the environment, including other organisms and projects associated with his name. Reporting focuses on the museum’s taxonomic work and the specimen’s long period in storage before identification, rather than on new field collection.
