Level 1 — Absolute Beginner
Sir David Attenborough is 100 years old this week. He is a very famous nature man on TV. Scientists wanted to give him a special gift.
They named a tiny new wasp after him. The wasp is called Attenboroughnculus tau. It is very small. It is just 3.5 millimeters long.
The wasp came from Chile, a country in South America. A scientist caught it in 1983. It then sat in a museum box for a long time.
Now a new study has shown it is a new species. The 'tau' part of the name comes from a 'T' mark on the wasp's body. The wasp is a birthday gift to David from the world of science.

Level 2 — Elementary
To mark the one-hundredth birthday of the British naturalist Sir David Attenborough, scientists at London's Natural History Museum have named a brand new species of parasitic wasp after him. The species name is Attenboroughnculus tau and the insect itself is only 3.5 millimeters long.
Despite being announced this week, the wasp has actually been quietly waiting in a museum drawer since 1983, when a researcher collected it in the Valdivia Province of Chile. Modern DNA tools and a careful look at its anatomy showed that nobody had ever formally described the species.
Parasitic wasps lay their eggs inside or on other insects. When the eggs hatch, the larvae eat their host from the inside. Although that sounds gruesome, these insects play a huge role in controlling pest populations naturally, without the need for chemical sprays.
Attenboroughnculus tau is the latest of dozens of species named after Sir David, from a 200-million-year-old fish called Attenborosaurus to a beetle, a butterfly, and even a long-horned grasshopper. The new wasp is a small but symbolic gift for one of nature's most influential storytellers.

Level 3 — Intermediate
On the occasion of Sir David Attenborough's one-hundredth birthday, taxonomists at London's Natural History Museum have formally described a previously unrecognized species of parasitoid wasp and christened it Attenboroughnculus tau. The 3.5-millimeter insect is the latest of more than fifty plant and animal taxa to bear the broadcaster's name, and arguably the smallest.
The specimen's path from forest floor to scientific spotlight is itself a parable about the world's museums. It was collected in 1983 in the temperate Valdivia rainforest of southern Chile by an entomologist whose interest had been winter beetles, not Hymenoptera. The wasp was pinned, labeled with a date and locality, and slid into a wooden drawer where it remained, formally undescribed, for forty-three years.
It re-emerged when a team led by Dr. Natalie Dale-Skey set out to revise the genus Diadromus, comparing morphology and short-read DNA across decades of accumulated specimens. The Chilean individual proved both genetically distinct and morphologically diagnostic, with a striking T-shaped mark on the abdomen that gave rise to the species epithet 'tau' — Greek for the letter T.
Beyond its symbolic value, the discovery underscores how much taxonomic work remains. Researchers estimate that roughly half of all insect species in the world's largest natural-history collections remain formally undescribed, awaiting the slow craft of comparative anatomy and modern molecular phylogenetics. Sir David himself has long argued that you cannot conserve what you have not yet named — a sentiment given a small but personal validation this week.

Level 4 — Advanced
To mark Sir David Attenborough's centenary on the eighth of May, hymenopterists at London's Natural History Museum have erected a new species of parasitoid wasp, Attenboroughnculus tau, an inconspicuous 3.5-millimeter inhabitant of the Valdivian temperate forest of southern Chile. The insect joins more than fifty plant and animal taxa already bearing the British broadcaster's name and, at a fraction of a centimeter, is arguably the most unassuming of the lot.
The holotype was collected on 27 January 1983 in the Valdivia Province by Spanish coleopterist Juan Llorente, whose preserve was the carabid beetles of the Nothofagus understory. The wasp was pinned, labeled with coordinates and elevation, and consigned to a wooden cabinet of Ichneumonidae oddments, where it lay formally undescribed for forty-three years — an unremarkable fate in a museum that conservatively estimates one-fifth of its 80 million specimens remain unnamed.
The species emerged from a recent revision of the cosmopolitan ichneumonid genus Diadromus by Dr. Natalie Dale-Skey and colleagues, who married classical comparative morphology with short-read COI barcoding. Pairwise genetic distances of more than seven percent to its closest known congeners, coupled with a diagnostically asymmetric T-shaped maculation on the third metasomal tergite, justified erection of the new species. The chosen specific epithet, 'tau', references the Greek letter T evoked by the mark.
Beyond the sentimental note, the discovery is a microcosm of a much larger problem in systematic biology. Roughly half of all insect taxa held in the world's largest natural-history repositories remain formally undescribed, blocked by the slow handcraft of differential diagnosis, the dwindling number of trained alpha-taxonomists, and chronic underfunding of revisionary monographs. Attenborough himself has long argued that the rate of biodiversity loss exceeds the rate of biodiversity discovery — a sentiment a hundred-year-old broadcaster might be forgiven for finding both pertinent and personally vindicated this week.
