35.0191 Anarsia innoxiella Gregersen & Karsholt, 2017

Status and Distribution

In 2017, Gregersen & Karsholt published a paper introducing Anarsia innoxiella as a species new to science (see under A. innoxiella in Publications - Published Papers, on this site). It had previously been present, undetected, within the species Anarsia lineatella.

Following extensive checks, including advice and assistance from one of the paper's authors, a good number of records of A. innoxiella in southern England have been confirmed from photographs, although more await confirmation.

Indications are that it is well established in south-east England and extending its range to the west and northwest (new to Wiltshire in 2018 and Berkshire and East Gloucestershire in 2019). Despite this it still seems to be local in its distribution.

Most light-trapped specimens of Anarsia lineatella are now thought likely to refer to A. innoxiella. However, as one confirmed A. lineatella was attracted to MV light trap in Dorset in 2003, any previous records without a supporting photo or specimen, should be considered as unconfirmed.

    Foodplant and Larval Feeding Signs

    In Europe this species is associated with Acer species, particularly Acer campestre (field maple).

    Hedgerows and woodland edges seem the most likely habitat for this species although all confirmed British records so far have involved moths attracted to light traps.

    Finding the Moth

     Searches for spun leaves from April to early June, with the aim of rearing the larva through, will hopefully prove that the species is resident in Britain.

    Flight Period

    Occurs at light from the end of June to mid-August and is presumably single brooded. In 2009 it was recorded at light in late May and there is also a record of an imago found on the Channel Islands on the 9th September 1962; the latter however gives no details as to the circumstances of its capture.

    There are still many records of light-trapped Anarsia lineatella on county databases submitted prior to the split of the two species. Recorders should contact their County Moth Recorder to advise if they are able to update the identification by reference to a specimen or a good photo. If this is not possible the record is best considered unconfirmed.
