The Cardinal Beetle (Pyrochroa coccinea) is a brightly-coloured red or orange beetle. It is approximately 20 mm long. It has a black face.
The Cardinal Beetle preys on other insects and is normally found on flowers at the edges of woodland.
The Cardinal Beetle is a strong flier. It is bright red; in that way it warns predators that it is toxic.
People often mistake the smaller Scarlet Lily Beetle, Lilioceris lilii, for a Cardinal Beetle.
Pyrochroa serraticornis, which is very similar to P. coccinea except it has a red head instead of a black one, is also referred to as a Cardinal Beetle.

The 2-dimensional red makes a nice contrast by the deep black lines and feelers.
