Rhagium mordax
This is a yellow beetle with brown and black mottling and two eye-like spots on its wing-cases. For a 'long-horn' beetle, it has relatively short antennae.
The adult favours open-structured flowers, particularly Hawthorn and umbellifers where it feeds on nectar and pollen. Can be found in woods and hedgerows in most parts of Britain and is most often seen around flowers or in hedgerows in country areas.
Adults are seen between May and July.
The larvae are found in the very rotten wood of most species of broad-leaved trees, especially just under the bark.
Widespread and quite common in Britain.
Occasional in Leicestershire and Rutland. There were a total of 34 VC55 records for this species up to March 2015.
