Davey, P., 2009: A local species in Britain, the larva feeding on the ripening seed capsules of bladder campion (Silene vulgaris) and sea campion (Silene uniflora). This highly distinctive Pug is very local in Dorset, and is yet another species that has probably declined as a result of loss of unimproved grassland on chalky soils. It colonises the following habitat types:

Inland Rare on chalky soil where bladder campion grows, often on roadside verges, although this plant rarely occurs in quantity, and changes in farming methods in the last century will undoubtedly have reduced populations overall.

Coast: The second habitat is coastal where sea campion grows on cliffs and within the tracts of unimproved dry grassland on Portland and on Purbeck (noted only from St Alban's Head and from Durlston to date).

It is recommended that County Council extend their 'verges of interest' initiative to include roadside verges that support bladder campion, and suspend mowing these verges until the larval stage has been completed, usually by the end of August. It is also recommended that this species be included as a target rehabilitation species within unimproved grassland habitat management plans. See also Marble Coronet2171.
