The Holly Blue occurs in a wide range of habitats, including hedgerows, field margins, woodland rides, gardens, and parks, including those in urban and suburban areas. In England, it often breeds in churchyards, many of which have Holly and Ivy. In Ireland, it is limited mainly to deciduous woods with Holly and, occasionally, country gardens.
