Dichrorampha sequana
This record describes Dichrorampha sequana (species). Recorded family: Tortricidae. Recorded order: Lepidoptera.
Identification and Appearance
Wingspan about 10 mm. This is one of the smaller Dicrorampha species and can be distinguished by the broadly rectangular cream-coloured dorsal blotch. It prefers unkept verges and embankments, where Yarrow is common. Flies in the afternoon and towards dusk. Adults are on the wing in June, and rest on the flowers of the foodplants. The larvae, rather like other Dichrorampha species, feed internally in the rootstocks of the foodplant, Yarrow. Occurring fairly locally in the southern counties, ranging to the Midlands and Wales. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as local. No additional images available for this species.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Dichrorampha sequana. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
