Chersadaula ochrogastra Meyrick, 1923
Taxonomy & Nomenclature
Last record: 1920's
Rediscovered on 3 February 2020
Patrick & Dugdale (2000:21) noted that the species had "not been re-collected to our knowledge". On 28 January 2020 the iNaturalist user "wild_wind" uploaded a photographic observation of a moth from 19 October 2019. On 3 February 2020, Dr Robert Hoare added a comment confirming the identity of the moth as Chersadaula ochrogastra, and adding "as far as I know this is the only record of this species since the 1920's". As a recognised expert, Dr Hoare's identification turned wild_wind's photograph into a Research Grade observation. Since then there have been a further 53 Research Grade observations of the species, with the initial rediscovery likely raising awareness about the species and what it looks like in life, over and above a dried museum specimen.
