Elophila ekthlipsis

Elophila ekthlipsis is a moth in the Crambidae family. It was described by Grote in 1876. It is found in North America, where it has been recorded from the Great Lakes area, including Indiana, Maine, Michigan, Minnesota, New Brunswick, New Hampshire, Ohio, Ontario, Quebec and Wisconsin. The habitat consists of ponds and marshes.

The wingspan is 18–26 mm. The wings are deep yellow with white patches rimmed by black lines. The hindwings have a broad white medial band and a patch touching the costa. There is a white subterminal band and yellow terminal band, both edged in black, on both the fore- and hindwings. Adults are on wing from June to August.

The larvae probably feed on Nuphar lutea and Sparganium species. They create a portable case.
