SAINT HELENA GIANT EARWIG

THE SAINT HELENA

GIANT EARWIG

 

1. The Saint Helena giant earwig, Labidura herculeana, grew up to 3.3 inches long, making it the largest of the 2,000 earwig species in the world. 2. The earwig gets its name from an Old English word, ‘ear wigca’ meaning ‘ear wiggler’ or ‘ear creature' because an old myth was that they crawled into people’s ear canals while they were sleeping. 3. The Saint Helena giant earwig was shiny black with reddish legs. They had no hind wings, but did have an elytra which are short modified forewings. 4. Earwigs use their pincers for protection. It is thought that the Saint Helena giant earwig was a target prey item for the now extinct Saint Helena hoopoe. 4. They were discovered in 1798, but forgotten for over 150 years when they were rediscovered in 1962. It was even thought to be a brand new species, though testing showed they were in fact the same species noted in 1798. 5. They lived in many environments around Saint Helena including rocky places in seabird colonies, gumwood forests, Prosperous Bay Plain, Eastern Arid Area of the island, and Horse Point Plain where they were last seen in 1967. 6. They lived under island stones or in deep burrows, only coming out at night after it rained to eat rotten vegetation. 7. Earwigs are known for being good mothers, guarding their eggs for several weeks, grooming the eggs to remove fungus and adding an antifungal chemical to them, and moving the young if they are in danger. 8. The last specimen was collected in 1967. 9. In 2023, Danniella Sherwood negotiated with the Royal Museum in Central Africa in Belgium to get an intact specimen of the Saint Helena giant earwig to be donated to Saint Helena’s museum as an act of repatriation.

EXTINCTION DATE

Around 1967

 

Saint Helena was first visited by the Portuguese on May 21, 1502. The island’s diverse species lived in isolation from other places for a long time. Saint Helena was used by the Portuguese, Dutch, and British, and that constant use had devastating effects on the species there. Famously, Saint Helena is where Napoleon was sent for his second exile in 1815. He later died there. The Saint Helena giant earwig, Labidura herculeana, was first discovered in 1798 by Johan Christian Fabricius and it was labeled a subspecies of the shore earwig. It was forgotten from the science community until it was rediscovered over 150 years later in 1962 by Douglas Dorward and Philip Ashmole. It was actually labeled as a new species, Labidura loveridgei, but comparative analysis in 1965 proved that this “new” species was actually the giant earwig observed in 1798. It was observed under boulders in the Horse Plain Point in 1965. It was last observed by scientists in 1967. The exact cause of its extinction is thought to be a combination of factors like the use of island stones for construction, which limited giant earwig habitat. The other culprit was invasive species brought to Saint Helena that devastated so much of the island’s wildlife, rodents, mantids, and the Scolopendra morsitans centipedes. In 1982 the Saint Helena Philatelic Bureau brought awareness to the Saint Helena giant earwig by commissioning a stamp in its honor. Several expeditions have tried and failed to find evidence of the existence of the giant earwig. In 2014, its status was officially changed from critically endangered to extinct. In 2023, the Saint Helena government negotiated the donation of an intact specimen from the Royal Museum for Central Africa to put on display in the Museum of Saint Helena. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The Saint Helena giant earwig might be a good candidate. Scientists would use DNA from the many specimens that are in various collections. There have been efforts to restore and conserve the ecosystems and species of Saint Helena that still exist there, especially in the cloud forests. To date, 36 species on the island have already gone extinct with many others facing extinction. If the Saint Helena giant earwig was brought to life, could it ever be reintroduced to its native homeland on Saint Helena in the South Atlantic?

The Saint Helena giant earwig's Lazarus Tale has yet to be written. Would it be able to thrive again on Saint Helena in the South Atantic if it did return?
