Cliniodes ostreonalis
oystershell metrea moth
Cliniodes ostreonalis is a small crambid moth originally described by Grote in 1882 as Metrea ostreonalis. A 1964 taxonomic revision by Munroe restricted the genus Metrea to this single species, though it was later transferred to Cliniodes. The species occurs in eastern North America with over 300 citizen science observations. It is commonly known as the oystershell metrea moth, though the etymology of this common name remains unclear.
