Davey, P., 2009: A widespread species in south-east and central England, local elsewhere in England and in Wales with a preference for coastal habitats, the larva feeding on the flowers and seeds of chamomiles (Chamaemelum nobile and Anthemis spp.) and mayweeds (Matricaria spp. and Tripleurospermum spp.). In Dorset, the moth is at low density on the coast including Portland where sea mayweed (Tripleurospermum maritimum) is a known foodplant. Elsewhere, the moth is noted occasionally from localities where pineapple weed (Matricaria discoidea) grows on toxin-free farm tracks and where the much-declined chamomile plant hangs on still on grazed heaths and commons. Larval populations suffer from a high mortality rate due to parasitism. Historic larval records from Purbeck follow: Norden, four larvae on the leaves of scentless mayweed (Tripleurospermum inodorum) growing among the clay works on 22 June 1900, Corfe Castle, two larvae on the leaves of scentless mayweed growing in the disused clay works on 2 July 1900, Swanage, larva on the leaves of scentless mayweed growing near the water tower on 2 July 1900, Studland, six larvae on the leaves of sea mayweed growing on shingle near the Red Rocks on 15 June 1896 (Reverend E Bankes).
