Classification

Family:Depressariidae
Subfamily:Depressariinae
Genus:Agonopterix
Species:atomella
Authority:([Denis & Schiffermüller], 1775)

Nationally scarce (Na) on rough grassland in southern England, from Dorset eastwards, as far north as Worcestershire and Cambridgeshire; apparently absent from the Midlands, but occurring again from Cheshire northwards to Northumberland; in Wales it has been recorded from Pembrokeshire and Monmouthshire (MBGBI Vol 4 part 1), a Priority Species within the UK Biodiversity Action Plan and listed as a species of principle importance in England in Section 41 of the NERC Act, 2006.

In Hampshire the foodplant of this species is local and the moth is even rarer: it has been recorded in the past from Botley Wood (1990) and Cranmore (1981). However, it was found at Needs Ore in 1985 and a one-day survey in June 2015 found 56 larvae in six locations, and it is likely still to be present. Records were absent from the Isle of Wight since 1969, before it was found to be relatively numerous in the Newtown Common area in 2013 and there have been regular reports since - the geographical proximity of this site with Needs Ore, a stone's throw across the Solent, is probably not a coincidence. Wingspan 18-21 mm. The most likely confusion species is A. scopariella, which see for differences. Larva feeds on Dyer's Greenweed, living within a spun or rolled leaf.
