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.

How to identify

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 Britain, both of which can be distinguished by their black heads. The Black-headed Cardinal Beetle is rare, but found in similar habitats to the Red-headed Cardinal Beetle; while the Scarce Cardinal Beetle is only found at a few sites in Scotland and Wales, where it lives in Birch woodland.

How can people help

The Wildlife Trusts recognise the importance of healthy habitats to support all kinds of species, so manage many nature reserves for the benefit of all kinds of wildlife. But these precious sites are under threat from development, intensive agricultural practices and climate change. You can help by supporting your local Trust and becoming a member; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.
