The tiny specimen was collected in Sarawak, Borneo, by British naturalist Alfred Russel Wallace around 1855-1856, but its significance went unnoticed for generations. Consisting of little more than a thorax and a pair of wings, it had even been dismissed by an earlier expert as unworthy of further attention. Modern DNA sequencing and research into its original labels eventually revealed its identity, allowing scientists to revive an entire moth genus. Alfred Russel Wallace's forgotten moth was found among millions of museum specimens The discovery came while Natural History Museum scientific associate Mark Sterling and senior curator Dr David Lees were examining a collection of small, snow-white moths from Southeast Asia. They were investigating several specimens that appeared to represent previously undescribed species when an old, damaged moth became central to their research. The specimen had originally been described in 1863, but its deteriorated condition made identification difficult. In 1927, moth expert Edward Meyrick had recommended that it was 'better neglected'. Sterling and Lees took a closer look after noticing clues on its original labels, which suggested a much more significant history. A tiny label connected the moth to Wallace's expedition in Borneo One of the specimen's labels carried the abbreviation 'SAR', which caught the researchers' attention. The letters stood for Sarawak, a region in what is now Malaysian Borneo that Wallace visited during his travels through Southeast Asia. The researchers compared the label with historical records and Wallace's own account of his expedition, published in The Malay Archipelago. His writings described collecting moths from a bungalow near Kuching, Sarawak, between December 1855 and January 1856. The location and other historical evidence helped Sterling and Lees establish that the damaged specimen had been collected by Wallace during that period, almost 170 years earlier.

Even though the moth was badly damaged, they were able to extract a tiny piece of its leg and obtain genetic information. The results showed that it belonged to the same species as more recently collected specimens from nearby Brunei. Further analysis established that the other moths under investigation also belonged to the genus Topiris. The findings allowed the researchers to resurrect the genus, which had effectively fallen out of scientific use following the earlier dismissal of the original specimen. The study was subsequently published in the journal ZooKeys. Image: Mark Sterling Eleven new moth species were named, including one after Greta Thunberg The research expanded Topiris into a group of 14 species, 11 of which were newly described by scientists. Among the newly named moths were species inspired by the fictional characters Snow White and Cinderella, while another was named in honour of environmental activist Greta Thunberg. The discovery demonstrated how historical museum collections can still contribute to modern scientific research, even when individual specimens appear too damaged to be useful. The butterfly and moth collection contains approximately 13.5 million specimens, representing more than 100,000 species. The Wallace moth's rediscovery showed that overlooked material stored in museum drawers can still hold important clues about biodiversity and evolution.
The unseemly haste with which five elephants from Assam were transported to temples in Tamil Nadu raises pertinent questions about the process of animal transfer, and whether the rules are cheat proof. Here, Geetha Srimathi examines the entire issue threadbare, explaining how elephants are acquired for temples in the State, and the yawning gaps in the rules, and processes that allow humans to ‘trade’ in pachyderms.
