Special features:  The mint leaf beetle, as the name suggests can normally be found in the summer months munching away at the leaves of various mint plants. Its whole body is a jewel-like iridescent green colour which is peppered with tiny little indentaions.  Both the larvae and the adult beetles feed on mint.

There is another similar looking species which also feeds on mint, but is an iridescent blue colour.  As you might expect it's called the Blue Mint Beetle (Chrysolina coerulans)
