Identification and Appearance
Wingspan 11 to 16 mm. This species is sexually dimorphic, with the males being generally larger and with less distinct forewing markings. The adult moths fly in May and June, from dusk onwards. The life history of the early stages is imperfectly known, though in captivity they have fed on Hawthorn. Locally frequent in parts of England, and occurring in Wales and Scotland. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as local.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Isotrias rectifasciana. 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.
