Elophila ekthlipsis

Elophila ekthlipsis is a moth in the Crambidae family. It was described by Grote in 1876.^[1] 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.^[2] 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.^[3]
