The Little Conch (Cochylis dubitana) is a moth of the Tortricidae family. It is found in China (Heilongjiang) and most of Europe.[2] It is also found in North America, where it has been recorded from Colorado, Maine, Ontario and Washington.[3]

The wingspan is 11-16 mm.[4] There are two generations per year with adults on wing in June and again in August.

The larvae feed on Senecio jacobaea. Larvae of the first generation first feed on the flowers and later feed in the main stem, causing a swelling. Pupation takes place in a yellowish brown cocoon within the stem. Larvae of the second generation feed in the stems and roots and overwinter. This second generation pupates in April.


The larvae feed inside the flowers and developing seedheads of various Compositae species, including Senecio, Crepis and Hieracium species and Sonchus arvensis and Solidago virgaurea. Larvae can be found in July and from August to April. They overwinter in a cocoon among debris. Pupation takes place from April to July in a cocoon on the ground among debris.[5]
