Stigmella samiatella
This record describes Stigmella samiatella (species). Recorded family: Nepticulidae. Recorded order: Lepidoptera.
Identification and Appearance

Wingspan 5 to 7 mm. This tiny purple-bronze moth is a member of the unicolorous ruficapitella group of Nepticulidae. The larva creates a quite long and contorted gallery mine in oak ( Quercus ) or sweet chestnut ( Castanea sativa) . The gallery is long and broad, frass dispersed in later part of mine. Can be recorded on Sweet Chestnut; mines on oak cannot be recorded unless adults have been reared and identified. There are two generations, creating leaf mines in June/July and September/October. This species was until recently poorly recorded in Britain. As more studies have been undertaken, it has been found to be more widely present than previously thought. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local. http://www.leafmines.co.uk/html/Lepidoptera/S.samiatella.htm https://bladmineerders.nl/parasites/animalia/arthropoda/insecta/lepidoptera/monotrysia/nepticuloidea/nepticulidae/stigmella/stigmella-samiatella/

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Stigmella samiatella. 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.
Recorded sources for this group: IUCN Red List, Xerces Society, USFWS, PNAS, WWF. Imported estimates may describe particular regions or reporting periods.
