Euchromius ocellea, the necklace veneer or belted grass-veneer,[2] is a cosmopolitan migratory species of moth of the family Crambidae, first described by Adrian Hardy Haworth in 1811.

[3] It is widespread in tropical and subtropical regions,[4] while it is a rare migrant in some other parts of its range, such as the UK[5] and the Netherlands.

[4][8] Goater additionally mentions fine silver streaking on the entire wing; golden metallic spots near the black terminal dots; and, in male specimens, a semi-transparant patch on the basal side of the cell.

[4] Schouten makes mention of a yellowish spot in the posterior area in some specimens.

In eastern Africa there seem to be two flight periods with adults on wing from November to February and again from June to July.
