Reference state 1 – Maritime heath with abundant devil’s-bit scabious and marsh fritillary butterflies

This form of maritime heath, with abundant devil’s-bit scabious (Succisa pratensis) can host large colonies of the marsh fritillary butterfly (Euphydryas aurinia). The scabious is the food plant for the marsh fritillary caterpillars and the larval webs of the butterfly (seen in the image here) can be abundant in good years.
