About Eudonia bisinualis Hudson, 1928
Eudonia bisinualis is a species of moth belonging to the family Crambidae. It was first described by George Vernon Hudson in 1928, and is endemic to New Zealand. This species was originally treated as a separate species due to its distinctively marked discal forewing streak. However, researchers have argued that it should be classified as the same species as Eudonia cymatias, pointing out that the wing patterning of this group is variable, E. bisinualis is outwardly identical in appearance to E. cymatias, and the male genitalia of the two supposed species are identical. Adults of Eudonia bisinualis are active and on wing from October to May.
