Agonopterix arenella is a moth of the family Depressariidae, found across Europe with the exception of the Iberian Peninsula. It was described by Michael Denis and Ignaz Schiffermueller in 1775 under the name Tinea arenella. The adult has a wingspan of 19 to 23 millimetres. The forewings are whitish ochreous, suffused and sprinkled with dark fuscous, with a spotted costa, a black first discal stigma and dark fuscous terminal dots, while the hindwings are a pale whitish fuscous. The larva is green with darker green dorsal and subdorsal lines, blackish dots and a light brownish ochreous head. Larvae feed on a range of plants including Arctium lappa, Carduus, Carlina, Cirsium vulgare, Knautia, Serratula tinctoria and Sonchus, mining the leaves of the host, and can be found from May to early August.
