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.

GBIF citizen-science records
It is estimated from how often the Mint Leaf Beetle is recorded against all the insects logged in Turin (14 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
