This large, beautiful moth, identified by the straw-yellow colour of its forewings, is restricted to only nine sites in the country, three of which are managed by Kent Wildlife Trust (Lydden Temple Ewell, Darland Banks and Queendown Warren). The Straw Belle is classed as a Priority Species in the UK Biodiversity Action Plan.
Butterfly Conservation carried out several Straw Belle surveys in 2021. The count of 123 Straw Belle on 23 August at Lydden Temple Ewell was the highest count of any single UK site in 2021, identifying the site as the best place for Straw Belle Moths in the country.
