Recent Status:Isophrictis anthemidella was established as a British species from two specimens captured in Kent during 2020. There are a number of very similar species of Isophrictis. The specimens captured in Kent were DNA matched to one of two DNA groups allocated to I. anthemidella. Entomologist’s Rec. J. Var.134: 7-15. The possibility therefore exists that the nomenclature may change in future. I. anthemidella was first recorded in East Suffolk by dissection during June 2023.
Life Style: The moth is single brooded flying by day and night and comes to light. It has been captured from June till August. It is possible that Suffolk records of Isophrictis species are primarily immigrants. The larvae feed on flower heads of Anthemis tinctoria, Leucanthemum vulgare and Tanecetum corymbosum.
Identification: A small narrow winged species with a silver line from the base to about one half, a black dot centrally around three quarters and descrete white markings in the terminal quarter. The palps have long forward pointing scales. Isophrictis anthemidella only differs slightly on superficial characters from I. striatella. The colour is a greyish rather than reddish brown and I. anthemidella has grey scales above the silver line that emanates from the wing base that are absent in I. striatella. There are other very slight differences. It is necessary to confirm a record of I. anthemidella by dissection. Images can be found at the following link More Info
