The tansy beetle[1] (Chrysolina graminis) is a species of leaf beetle. The common name derives from its main foodplant, Tansy (Tanacetum vulgare), but it can also use other wetland plants such as Gypsywort (Lycopus europaeus) and Water Mint (Mentha aquatica). It measures 7.7–10.5 mm in length and has a characteristic bright metallic green colouration, with pitted elytra and a coppery tinge. In addition to the nominotypical subspecies, which repeats the specific name, C. graminis graminis, there are five further distinct subspecies of Tansy beetle, which, collectively, have a Palearctic distribution, although in the majority of countries where it is found the species is declining.[2] In the United Kingdom it is designated as 'Nationally Rare'.[1] The stronghold population here is located along the banks of the river Ouse in York, North Yorkshire.[3] Other, small, fenland populations exist at Woodwalton Fen and at Welney Wildfowl and Wetlands Trust (WWT) reserve.
