Macro photography || Blue mint beetle (Chrysolina coerulans)

Chrysolina is a large genus of leaf beetles in the subfamily Chrysomelinae. Most of the species are well known in Europe, Asia and Africa with a small number of species inhabiting North America (including introduced European species) and species produced in Australia. The species Chrysolina cerealis and C. graminis are protected in the UK. All suitable Chrysolina species feed on certain food crops, and some of them have been used for biological control of weeds. In order to control Hypericum perforatum (St John's wort), C. hyperici was successfully naturalized in Australia in the 1930s and several species, notably C. quadrigemina, were introduced to California in the late 1940s. sources

These insects are difficult to find using a standard cellphone lens because the object is super small, so to get a good picture you have to combine a camera with a macro lens.
