Melanocoryphus albomaculatus is a ground bug 7 to 9 mm long, with a black head, antennae and legs and a red pronotum marked with two hook-shaped black spots. The forewings are red with a black spot in the centre, and the membranous wingtip is black with a single round white spot.

It feeds mainly on the seeds of swallow-wort, with foxglove and ragwort also used as forage plants, and favours hot, dry, stony ground, sometimes on sandy soils. The species is common around the Mediterranean and extends east through Asia Minor to the Caspian region, active from February to October.
