About

The red-headed cardinal beetle is a medium-sized beetle found in woodland, along hedgerows, and in parks and gardens. The adults are present during the summer and can often be found sunbathing on flowers or tree trunks. They are predators and feed on other insects flying around the flowers on which they are perched. The larvae are flattened in appearance, which enables them to live under loose bark where they feed on the larvae of other insects.

What to look for

The red-headed cardinal beetle is bright red, with black legs and long, black, toothed antennae. There are two other species of cardinal beetle in the UK, both of which have black heads. The black-headed cardinal beetle (Pyrochroa coccinea) is less widespread, but found in similar habitats; while the Scarce cardinal beetle (Schizotus pectinicornisis) is only found in Birch woodland at a few sites in Scotland and Wales.

Where to find

Found in England and Wales.

Did you know?

Red-headed cardinal beetles are similar to lily beetles in appearance, but the latter have a much more rounded body and their wing cases are covered in dimples. The lily beetle was introduced into the UK in the 1900s, arriving on imported flowers.
