Taxonomy
This species was originally described by Francis Walker in 1863 using a female specimen collected by Dr. A. Sinclair in Auckland and named Crambus sabulosellus. In 1884 Edward Meyrick discussed the species giving a more detailed description, placing it within the genus Scoparia and changed the ending of the species name from the masculine -us to the feminine -a. George Hudson discussed and illustrated this species in his 1928 publication The Butterflies and Moths of New Zealand also under the name Scoparia sabulosella. In 1988 John S. Dugdale placed the species in the genus Eudonia.
Description
Walker described the species as follows:
Female. Cinereous fawn-colour. Labial palpi a little longer than the breadth of the head. Abdomen extending a little beyond the hind wings. Fore wings narrow ; discal point and marginal points black ; exterior border almost straight, slightly oblique. Hind wings pale cinereous. Length of the body 4+1⁄2 lines; of the wings 10 lines.
This species is variable with some specimens being much darker than others. However, despite this E. sabulosella can be distinguished from similar species as it always has a pale ochreous ground colour to the forewings along with two distinct blackish dots.
Distribution
This species is endemic to New Zealand. It is generally distributed throughout New Zealand and can also be found on the Chatham Islands, Stewart Island as well as in the Auckland Islands.
