Elophila rivulalis

Elophila rivulalis is a species of moth in the family Crambidae. It is found in the Ireland, Netherlands, Belgium, France, Germany, Poland, Austria, Hungary, Croatia, Italy and Greece.

The wingspan is 20–25 mm. The body and wings are white and have a pattern similar to that of Elophila nymphaeata. The markings have a more grayish-brown tint and are greatly reduced compared to the similar species. A relatively reliable distinguishing feature is the comparatively small discocellular spot on the hind wing. This is usually filled with white on the inside and clearly separated from the distal line. The submarginal area of both pairs of wings is very pale, pale grey tinted and bordered by grey spots inside. The fringe scales are slightly speckled. The R2 vein originates separately at the discoid cell of the forewing. Distally, it merges with the R3+4 vein for a short section and then separates from it again towards the wing edge.
