Mint Leaf beetle

The species is generally metallic bright green, with some of the mint leaf beetles having a gold-purple reflection. Variations in colour exist, with certain specimens, in particular females, ranging from golden-red to deep blue. The beetles' legs and pronotum are the same as their basic colour, and they have antennae. Chrysolina herbacea is large and has a long, oval shape. The adult beetles can be 8–10 mm long and have black-coloured larvae, which also feed on mint leaves. The adults have complete wings, but they only seldom fly. Visually, the mint leaf beetle may be confused with the much rarer tansy beetle (Chrysolina graminis), as well as with Cryptocephalus hypochaeridis, and with Chrysolina coerulans.

The species can be found in the European islands Great Britain, and Ireland, in European countries such as Portugal, and Romania, as well as in the Caucasus, Turkey, western Central Asia, and North India.
