This is a distinctive black and white shieldbug. Length 7mm.
It feeds on the seeds of White Dead-nettle and Black Horehound.
The adults can be seen all year round, but especially in the spring when they emerge in fair numbers from hibernation. Found on nettles and similar plants, in hedgerows and woodland margins. Common and widespread in southern England and much rarer further north, and absent from Scotland and Ireland.
