Anarsia innoxiella

Alternative names
Acer Sober

Wingspan 11 to 14 mm. The long black streak in the centre of the forewing is said to be diagnostic of innoxiella, supported by the more contrasting pattern overall.

Similar Species

Anarsia lineatella is similar but has a less-contrasting, duller pattern and the central black streak is shorter and more elliptical.

Identification difficulty
Recording advice

Please provide good photographs and retain the specimen. Gen det may be needed for species confirmation.


The species is associated with Acer.

When to see it

Adults are typically on the wing in July and August.

UK Status

Status is difficult to determine, but the species appears to be well established, if local, in southern England at least. This species was recognised as new to science in a paper published in 2017, and it is thought that most specimens of previously identified A. lineatella that have been light-trapped are likely to be innoxiella.

VC55 Status

Rarely recorded in Leicestershire and Rutland.
