Raglius alboacuminatus
Family: Lygaeidae

A medium-sized ground bug which has striking red-brown and white markings on the forewings and rear third of the pronotum. There is a large white spot on the cuneus. Both macropterous and brachypterous forms occur. 

A scarce species which is found mainly in southern Britain, particularly the south-east. The main foodplant is black horehound and the bug favours dense stands growing on sparsely-vegetated ground.  It has been mainly recorded from ruderal habitats such as wastegrounds, roadside verges and woodland clearings.

Adults overwinter, mating in the spring, when they may be active rather early in the year. The new generation is complete from late July onwards.
