Lepidoptera The Grass Rivulet Moth – Emmelesia Albulata
We represent the genus Emmelesia by the Grass Rivulet-a pretty little moth that flies in June, and which is widely distributed though not abundant.
Its fore wings are pale grey, crossed by several white lines, the arrangement of which may be seen in our engraving. The hind wings are of the same ground colour, but have no markings except a white wavy line near the hind margin.
The caterpillar feeds during July and August on the seeds of the yellow rattle (Rhinanthus Crista-galli), protecting itself from its enemies by spinning together the petals of the flowers; and when full grown it changes to a chrysalis under the same cover.
