About Aethes margaritana (Haworth, 1811)
Aethes margaritana, commonly known as the silver coast conch, is a moth species belonging to the family Tortricidae. This species was first described by Adrian Hardy Haworth in 1811. It can be found across most of Europe. Its typical habitats include downland, waste ground, and shingle beaches. Adult moths of this species have a wingspan ranging from 12 to 16 millimetres (0.47 to 0.63 inches). The species produces two generations per year, with adults active on the wing first from May to June, and a second generation from July to August. The larvae of Aethes margaritana feed on species from the genera Chrysanthemum, Tanacetum, Achillea, Matricaria, and Chamomilla. The larvae reside within the flowers and seeds of their host plants. This species overwinters in the larval stage, and pupation takes place within the larva's original habitat during spring.
