When first discovered this particular species was though to be the American representative of S. littoralis as the two species have very similar forms. However, S. ornithogalli is known to have much darker color body with sharper markings.[1]

Description

The wingspan of the adult moth is 32–44 millimetres (1+1⁄4–1+3⁄4 in). The fore-wing is brown with tan markings and a blurry white stripe coming from the wing tip. The hind-wing is white with a thin brown margin. Larvae are black with thin yellow stripes on their sides.[2]

Adults are on wing from April to November depending on the location.

Europe

There were repeated port interceptions throughout 2020, especially on consignments of asparagus from the Americas.[3] Nonetheless so far S. ornithogalli remains otherwise absent from Europe.[3][4]

• Denmark: Phytosanitation interceptions only.[4]

Asia

• Japan: Phytosanitation interceptions only.[4]
