Norfolk status Very similar to Five-spot Burnet (trifolii) and can sometimes not be possible with one individual. To be safe, the population itself should be studied with foodplant and flight times noted if possible. It should then be apparent as to the identity of the population. Even then more than one species may be present so extra care should be taken.
Middle pair of spots tend to not merge as in trifolii but variation can occur, apex of forewing more pointed and black terminal band on hindwing narrower.
Grassland, uncut road verges, embankments, woodland and marshes.
Rare aberration in which the usual black ground colour etc. is replaced by a beautiful chocolate violet-grey colouration, observed at Sheringham in 2009.
